At least in my workflow, I only do scratch builds before pushing,
to ensure that what I am about to push builds correctly in Koji.
Same here. Some of
my packages are prone to break and in need
of patching on non-x86_64, so that's my main use case as well.
Never used "fedpkg scratch-build" since I didn't even know it
existed, but yes, having it be equivalent to "fedpkg srpm &&
koji build --scratch ..." would make sense to me.
A.FI.
