I really get the feeling you have no desire to understand what I'm talking about.

In case you've completely missed the entire conversation; we're talking about differences between cores in heterogeneous systems that have never existed for 80x86 before (and remain unaddressed for ARM big.Little), including "same ISA, different instruction timings, different cache sizes, ...". We have never had a situation where AVX2 is supported on some cores but not others in the same system.

My "optimize between caller and callee" is the entire reason every major compiler has adopted link-time optimization or link-time code generation (to allow the compiler/linker to optimize even when something is in a different compilation unit). There's currently no equivalent for shared libraries (e.g. like compiling byte-code when software is installed and/or libraries are updated, so that shared libraries can be statically linked and whole program optimization is possible).

Modern compilers auto-vectorize everything they can; and while they could do a better job at it the main problem is that programmers don't let the compiler optimize because they want to publish a single "generic, for all 64-bit 80x86" executable.

For some reason you think my "libraries keep doing what they do now (using the common subset when ISA is different)" is completely different to your "libraries keep doing what they do now (using the common subset when ISA is different)"?

Heh, no. You're just a patronizing fool struggling with reading comprehension, who thinks that alternatives to how things were done in 1960 should never be considered regardless of how much hardware and software has changed since.

For AVX-512, the reality is that it's too early for a software developers to publish a "compiled for AVX-512 generic executable for 64-bit 80x86" because they'll lose about 90% of the market; and that this availability/adoption problem (which will take about 10 years to dissolve, the same as it did for AVX2 and SSE before that) still has almost nothing to do with support for dissimilar cores we're talking about.
