That doesn't seem to have been an issue for recent new CPU architectures. RISC-V has excellent Rust support for example.

Not really. Rust still doesn't support Arm SVE or RVV intrinsics.

		I suppose so. I'd see that as more of a missing Rust language feature (SIMD support is still immature) rather than a platform support issue though.

		Neither does C, the regular ISO C as defined by WG14.
