Like C++? Not afraid of quirky build systems? Seeking LLVM co-maintainers

That would only make it worse, for surely x86-32 and x86-64 would be
whitelisted, so most developers would "just use clang anyway" and not
realize the problems they're causing.

The issues are how to stop developers and/or packagers from
arbitrarily bringing in new dependencies that (1) aren't supportable,
and (2) aren't desirable, and how to decide what dependencies fit
those categories.
