Relevant FESCo discussion and decision:
https://pagure.io/fesco/issue/2569#comment-713002
The text that was voted on:
Libraries packaged in Fedora may require ISA extensions, however
any packaged application must not crash on any officially supported
architecture, either by providing a generic fallback implementation OR
by cleanly exiting when the requisite hardware support is unavailable.
It is still stuck in the pipeline to get the packaging guidelines
changed, though:

Hope that helps.
