Erm, no?

It's the run-time dispatch (e.g. choosing which version of functions to use based on CPUID results) that some compilers (ICC) have been doing for ages; but slightly modified to work with dissimilar cores by making it more fine grained (not once at program startup, but "anytime where needed") and preventing scheduler from migrating to a different CPU type at the wrong time.

It's the "developer controls nothing, generic app designed for any/all 80x86 CPUs adapts to whatever it happens to find itself running on" model (the opposite of the "embedded environment where you control everything" model).

Is this because you have a single CPU affinity trying to do the job of both "user configured affinity" and "software controlled affinity", so that changing one messes up the other? If you had 2 separate affinities (where scheduler combines both with bitwise AND before making decisions) this wouldn't happen, and library functions could save the old "software affinity", modify it, do what it likes, then restore the original "software affinity" before returning to its caller; without messing up "user configured affinity".

Of course kernel could simply provide an "enable/disable migration to different CPU type" system call that doesn't use CPU affinity (possibly built on a "number of times disabled" counter so migration is only enabled when the counter is zero, and nesting works).

I think you're starting to conflate 2 different things here - the availability/adoption problems of AVX-512 (which is no different to the introduction of any ISA extension, which is something that's probably happened at least 100 times over the last 50 years); and the "dissimilar CPUs" stuff where "AVX-512" is merely a convenient placeholder representing any and all differences between cores (including instruction timings), for any ISA from the past, present and future.

I think "general purpose" is merely a synonym for "many special purposes superimposed".

I think AVX-512 is mostly an inevitable continuation of the "64-bit MMX -> 128-bit SSE -> 256-bit AVX2 -> 512-bit AVX-512" sequence, where SIMD width doubles every 5 years or so.

I also think one of Intel's recurring flaws is ruining useful things by relegating them to a "HPC niche" (and sometimes a "server only niche") to stifle adoption.

I don't think AVX-512 was designed to scale down to today's small CPUs; I think AVX-512 was designed to stay the same size while people's concept of "small CPU" expands and becomes what we'd consider "large" today. Moore's law isn't dead yet. I'm guessing that by 2025 the E cores will support AVX-512.
