Correct, git and trac aren't entirely orthogonal, but you're right
there's a discrepancy. My preference would be to move even further
away from forcing a trac-based workflow 'cause with git you're not
forced into using one workflow/set of tools and the skills are
transferable (in and out) and there's a lot more resources out there.

So I would propose that every *commit* that goes into Sage needs to be
positively reviewed. Tickets are (possibly changing, typically
monotonically) sets of commits, excluding the commits of dependencies.
Setting a ticket to positive review marks the current set of commits
as positively reviewed; if this set changes (due to changes in
dependencies or further work) this positive review is automatically
set back, but the commits that were previously reviewed are still
marked as such.
