AVX2 is much more prevalent than AVX-512 and thus tenable to require. RHEL is switching to x86-64-v3 baseline, for instance, which requires AVX2. AVX-512, on the other hand, has been moving backwards since Intel has not shipped any consumer-level CPUs with it for years now. The Steam Hardware Survey has AVX2 at 95.4% while AVX512F is still far behind at 23.9%.
