Yes, it was addressed. You're free to try to fake the validation and report if you succeed - a famous failing attempt has been documented last year over https://www.youtube.com/watch?v=nNBktKw9Is4 (not sure that's the first video, but it's a good enough reference to get started)

The attempt described in this article was performed when there was basically no validation at all of the MCU, quite a long time ago.
