Oh yes, as long as the anti-patterns that emerge don't cause other bugs, they're OK; but some may lead to logical bugs. I'm not sure how likely that is, though- not enough history to go off of yet.

Rust is certainly a step in the right direction. I hope the toolchain and so forth end up in a state where all forms of users can love it, though; I have seem some reasonable opposition to including Rust in kernel code, and that sucks.
