There are several reasons why the mEDBG does not perform to the same level as the EDBG/Atmel-ICE.
I can't really list everything here, but the short answer is that the EDBG/Atmel-ICE are more polished products than the mEDBG.
It has nothing to do with deliberately keeping it slower for the sake of sales, but rather the time spent on the mEDBG implementation vs the EDBG/Atmel-ICE implementation.
Edit: Even though the firmware binary is 28657 bytes, keep in mind that there is also a 4k bootloader in there, which leaves about 15 bytes of flash :)
Ah-ha. That was my understanding. i.e. the 32u4 was full.
.
At some time in the past, I had an XMINI that or AS version that would not update the firmware.
I had to solder a 0.05" header and replace the firmware directly with an ATMEL-ICE. As far as I can remember the binary was almost the full 32kB.
.
Anyway the XMINI updated properly after this. In practice it is easier to develop with ATMEL-ICE and regular external AVR board.
For a trivial mod, the XMINI works well enough.

David.
The STK500 has only got an 8kB AVR. To fit encrypted bootloader as well as the application firmware.
.
The real mystery is the Dragon. It seems to have "big enough" chips. But moderate performance.

This datasheet doesn't have the memory map diagram in section 6.2, while this one has a ridiculously small diagram. These are the new Microchip style datasheets, I suppose they decided they must be less than 500 pages at any cost. I'm all for more compact documents, but not sacrificing readability like this.
I guess they use the same cut and paste guy as Atmel :(
Fig 8-4 has addr of registers (that don't exist), so this is still cut and past cut and paste ............
About the encryption, it seems only the "good stuff", like Atmel-ICE firmware, is encrypted.
Oh no, you figured out our big secret that the mEDBG is not encrypted :)

Atmel gave us all answer:
Though, there is minor "thing" with EEPROM, which I'm gonna save for myself for now...
This may or may not be the EEPROM map for the mEDBG, the aboslute address for each field in the EEPROM is (512 * bank) + address.
The important one to get right for homebrews is FIRE register which tells Atmel Studio which firmware image to use when the tool is upgraded.
The serial number, kit name, manufacturer name and target name are ASCII '\0' terminated strings.

Sheet, page 19:
General Purpose I/O Registers
The ATtiny417/817 devices provide four General Purpose I/O Registers. These registers can be used for storing any information, and they are particularly useful for storing global variables and interrupt flags. General Purpose I/O Registers, which recide in the address range 0x1C - 0x1F, are directly bit-accessible using the SBI, CBI, SBIS, and SBIC instructions.
(The spelign eror is Microchip/Atmels, not mine.)
As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here.
No guarantees, but if we don't report problems they won't get much of a chance to be fixed! Details/discussions at link given just above.

[C Lawson] "There are always ways to disagree, without being disagreeable."[E Weddington] "Words represent concepts. Use the wrong words, communicate the wrong concept." [J Morin] "Persistence only goes so far if you set yourself up for failure." [Kartman]
Add support for the UPDI interface. This programming and debugging interface is used in the AVR8X (2017->) series of devices and is supported in JTAGICE3, AtmelICE, EDBG, mEDBG, nEDBG and PowerDebugger.
Specification is located here: (will post a link when it finally goes public)
By adding support for UPDI it opens up for supporting the AVR8X range of devices; ATtiny212 - ATtiny416 - ATtiny817 - ATtiny1617 - ... (To be continued)
The chip programmer now supports AVRISP MkII, AVR Dragon, STK600, JTAGICE mKII, JTAGICE3 and AT ATMELICE without the need for Atmel Studio to be installed
#5 "If you think you need floating point to solve the problem then you don't understand the problem. If you really do need floating point then you have a problem you do not understand."
I found a small error in the datasheet, in the UPDI chapter.
This is part of the procedure to program the User Row on a locked chip, via UPDI:
But in the relevant register, this bit is described as read only. This is an error; I've verified that this bit is indeed reset by writing a '1' to it, so it should be R/W in the datasheet, with the usual note that it is cleared by writing a '1', like several other AVR flags.
I found a small error in the datasheet, in the UPDI chapter.
Nice. Assuming that the procedure was written correctly to begin with, and that the error is indeed an error based on that assumption, then the same applies to the ATtiny1614/1616/1617 datasheet as well.
You found it, have you written up a support ticket yet?
EDIT: Morten please add the ATtiny1614/1616/1617 datasheet to the report.

Actually, I'm not exactly sure of the best way to report datasheet errors. I don't feel so comfortable sending this to some generic Microchip mail, will they read it?
I know some former Atmel people are active here, so I report them here, at least they are visible to everyone.

I'm using attiny814 as my target dev. I'm in progress to build programmer for updi mode.
I had design 5 modes (ISP, HVPP, HVSP, PDI,TPI[lo & hv]). UPDI is the last mode.
I need more avr chip for testing and added to programmer database. I'ts hard for me to get samples where I leave (in Indonesia), may be anyone can help me to get sample from Microchip.
I'll publish lite version after finishing UPDI mode.
PC software created using Lazarus (can be compiled for windows, linux, mac), for now I had only windows.
Also I hope can build for Android too, that support usb host (usb otg)
