I still have serious concerns regarding build times:
* arm - https://arm.koji.fedoraproject.org/koji/buildinfo?buildID... ~ 17h
* current primary - https://koji.fedoraproject.org/koji/buildinfo?buildID=429023 ~1h 30m

This is still too huge gap - roughly 10 times slower. If ARM will become primary arch I hope this
is an exception and not the general rule.
