Fuses - How Do They Work?
Agreed. I think "non-volatile configuration bits" would be a good phrase to describe them.

Full wave rectify with a schottky bridge into an opto-isolator?   Edit: would only work with single ended signal.  True differential would be a no go.

mega0/xTiny Full Chip Erase possible from application section?
My read of the data sheet suggests that the bootloader sets the BOOTLOCK bit in NVMCTRL.CTRLB register if it wants the bootloader section to be protected.  I guess they leave...
