> Many people already use non-portable SIMD for the 1-3 targets they care about, instead. This is something a lot of people (myself included) have gotten tripped up by. Non-portable SIMD intrinsics have been stable under std::arch for a long time. Obviously they aren't nearly as nice to hold, but if you're in a place where you need explicit SIMD speed-ups, that probably isn't a killer. |

The thing that isn't stable in the standard library is the portable abstraction layer atop those. But several of those exist in the community.
