What I am trying to say is almost all of these "SIMD" libraries were done to wrap x86_64 SIMD and is almost done in a bad form in general. I noticed that when working on AARCH64 (even before SVE). they push the idea of a low level wrapper just because "it is easier" rather than higher level concepts. xsimd, even the whole C++ SIMD library seems to push low level wrappers rather than high level concepts that could be optimized.
