So it seems safety guarantees are still not assured - there should be some sort of formal proof/verification metadata extension for Rust that allows unsafe regions to be proven safe. Otherwise I consider these to be "cheating"

Cheating? Look who's talking!

Well, there is still the same "unsafe code" issue with the vibe-coded decompilers you posted last week:

This is always a problem with vibe-coded content.

OTOH, at least the nanokrnl above is a excellent proof-of-concept of something that was only a pipe dream for many years.
If you've actually read the whole article carefully, you can see that it was meant only as a PoC and not for production use anyway!

A nano Windows kernel booting through a hand-built emulator in the browser, on its own NT syscalls, is quite an achievement.

Kudos to the creators of the nanokrnl projext!
