AFAIK there's existing microarchitectural optimizations in gcc and clang already, so it's reasonable to assume that AMD would add just such a feature.
But most people don't enable these features when building because they often make the resulting executable/library unusable on general CPUs. However, businesses/individuals with more specialized needs and better control over their targets often do capitalize on these.

Back in the days of compiling MySQL myself, it was worth doing. But at some point They hardware cluster was not identical, and so I scripted builds and each machine built its own.
