I think we should try to do frequent ungrafting branches, at least for
non-core packages like python-pillow. We have the build capacity.

The Cuirass web interface is not as helpful or detailed as that of
qa.guix.gnu.org, and QA cannot currently build such large changes, but
we should still create and try to build these branches.
