Yeah I guess patchwork is more reflective.

I sometimes put things in next for a few days to see if any issues shake
out, before I update patchwork. Mainly because it's a pain to un-update
patchwork if the patch needs to be backed out, but also as a signal that
the patch isn't quite locked into next yet.
