Packages optimized for very specific x86_64 "x" generation (OpenSUSE OBS / Fedora Koji)

As darktable co-maintainer, today I was speaking with darix from
OpenSUSE community, which maintains such package on that distro.
On their OBS build system, they are able to build various packages each
one optimized for a single x86_64 CPU generation using @BUILD_FLAVOR@ +
_multibuild file.[1] So for example they have packages

 darix also said "that is an OBS feature, nothing that you can just copy
to koji[...]"
"there is no generic solution to this for a normal distro package".

I would like to study a way to make darktable (sub)packages very
optimized for each CPU generation, so I am asking you if that is
possible on Fedora, and what I should study to achieve it.

Best regards

On Fedora 27+ (glibc 2.26+), you can use the standard way of building
optimized libraries and putting them in platform and capability-specific
directories, e.g.:

It's not the same as OBS does, but it's better than nothing.
