They could at least have locked down the flash and RAM, triggering a flash mass erase when attempting to dump the firmware/RAM contents. Not that this would be 100% secure either, but with these STM32 HW features in place this is already significantly more difficult.

I don’t see how making it harder to dump the firmware makes the platform any more secure. Determined attackers will get in anyways and you’ll lose out on people who are interested in poking around.

It's usually done to prevent cheap chinese clones of your boards, not so much for security.
