The CPU-specific intrinsic stabilized a little while ago for cases where you need SIMD on a specific platform at least. A lot of crates like glam seem to only support SIMD on x86/x86-64 for that reason.

I know that `wide`, `faster`, and `simdeez` are options for crates to do cross-platform SIMD in safe Rust. Eventually we'll have `std::simd`, but I don't know what the timeline is or what the blockers are.
