Right, I was making a ha-ha-only-serious thought that perhaps there
could be a spin that is specifically highly optimized for
latest-n-greatest architectures, and if packagers want to maintain two
different versions of x64, that’d be their choice, otherwise fallback
to the ‘regular’ one. It certainly wouldn’t be the most popular,
but for the folks who could stand to benefit from it, they’d know
where to find this particular spin.

It's not as simple as a "CPU newer than date X" cutoff -- Intel limits
AVX support to their Xeon and Core brands only. Their current-gen
lower-end stuff (sold as Pentium, Celeron and Atom) doesn't support
AVX of any flavor. And they sell a _lot_ of those.
I think AMD's situation is a bit better, with all of their current
processors supporting AVX, and only one (Family 16h) lacking AVX2.
