But this isn't about code style for a repo. If folks don't use the rust code style for contributing to the rust repo, sure, their pulls will be asked to fix it and not merged till they do.

But as you yourself mention, folks use different code styles in different places. This is about being clearer about that.

The better analogy here is GCC calling non-GNU style C code "bad" in all repos it is run on.

Rust as a community is much more uniform wrt code style than C is, which is why the compiler even does things like warn about nonstandard style, but that's just it -- the style is non standard, not intrinsically bad in anyway (and "nonstandard" is better at explaining what's wrong than "bad" is).
