Yep, testing non-pushed content is the primary reason for doing a
scratch-build. So 95% of the time I'll use  "fedpkg scratch-build --srpm"
on non-pushed content. Very occassionally I'll do a scratch build
with pushed content, if testing compat with the latest build root
contents.

Probably 70% of the time I would often also add  "--arch x86_64" to
avoid burning CPU time across all the Fedora arch builders for a plain
smoketest. Sometimes might pick a different arch if chasing a particular
arch problem.

With regards,
Daniel
