Type-C "configuration resistors" replace "termination resistors"?

Hi! question, I'd like to use a USB-C receptable on my PCB (with a Atmega32U4), and it ought to be connected to an ancient legacy USB-A-V2.0 host port on the PC. Do I still need termination resistors on D- and D+, or are they now obsolete using USB type-C? I know that USB type C wants those 5.1K pull downs on CC1 and CC2, called "configuration resistors". But I'm not sure if they replace the former 22R termination resistors on the data lines, or not?

This topic has a solution.

Termination resistors are an electrical requirement and are still necessary.

My experience with USB Type-C is the connectors will de-mate with wear.

If can spare the space then USB type A or B in high-retention else micro B.
