I'd argue that this should've been submitted as a System-Wide Change. If I understand correctly, this change would affect every package that is built on s390x? As such, it would've been way too late for Fedora 37, as it should also have been ready before the mass rebuild. And I'd also argue that not having this change ready before the mass rebuild, and only pushing selective builds is not a good idea. If there is fallout from this change, it would be better to catch it at or before the mass rebuild. Otherwise, if the switch is made *after*, potential breakage could well happen over the whole lifetime of Fedora 37 (i.e. after GA and until EOL), as more and more packages are rebuilt, which would be a completely unpredictable source of issues.
