I agree, in principle, any optimization crafted to AVX2 is also applicable to AVX512 target, in future with AVX10.2 (converged ISA) we will have a 256bits flavors of two table permute for non-AVX512 targets, for now AVX-SHA512 is only available on client parts (upcoming Lunar lake) and its ok to follow the IPsec algorithm in toto.
