> but Intel now has AVX 10.1 and 10.2 in addition to the base set

Intel committed to not slicing and dicing the AVX instruction set going forward. AVX 10.(n+1) will not remove instructions that were in AVX 10.n. Feature testing is also easier: a single feature bit and a single version number.

I bet Intel's management will find some new counterproductive way of segmenting the market but AVX-10 (and therefore AVX-512) should be safe now.
