Weird architectures weren’t supported to begin with

This is the heart of the conflict: Rust (and many other modern, safe languages) use LLVM for its relative simplicity, but LLVM does not support either native or cross-compilation to many less popular (read: niche) architectures. Package managers are increasingly finding that one of their oldest assumptions can be easily violated, and they're not happy about that.

But here's the problem: it's a bad assumption. The fact that it's the default represents an unmitigated security, reliability, and reproducibility disaster.

I'm sure this will go down well.
