It sounds reasonable - you don't waltz into a large existing project $FOO and tell the existing maintainers "Here's our rules going forward - you shall learn $BAR!"

It's both rude and arrogant.

I have not seen any good arguments for why there should be an exception when $BAR == Linux and $FOO == Rust.
