I'm using this comment as jumping point.
What's cost/opportunity to optimizing for a specific platform/instruction set ? At what point is it worth doing, when isn't it worth doing ? AVX-512 strikes as something... "ephemeral".

Sure AVX-512 is only applicable to specific workloads, and even many of those workloads the cost/opportunity of optimizing for AVX-512 might not be worth it. But there clearly ARE usecases that would benefit, and it might be worth it for more consumer applications to optimize for AVX-512 - but only if it can be used.
The way I see it is that the benefit of optimizing for AVX-512 is far higher if it becomes normal for consumer CPUs to have it. A 28% improvement is pretty decent, but it's only worth implementing if enough people can utilize it.
