There's not much use for AVX-512 in the kernel. But, from the people who are using it I've heard good things. It's an enormous collection of new instructions. But, a lot of them came from the Larrabee team --which was probably the greatest case of high-perf software engineers having direct influence over the direction of a CPU. Otherwise, the history SSE and AVX has largely been software engineers requesting features and hardware engineers replying "Do not understand. How does that feature improve our SPECfp score? Rejected."
