> That said, I want all teams to squash merge their feature into master after tests pass. One commit at the end, and one commit to remove in case of an issue affecting customers related to the release.

This is the one thing I always point to when I say "Mercurial is better" (and now, jj).

Why can't we have our cake and eat it? Mercurial lets you have lots of individual commits, but they're hidden, and you'll see only the squashed commit. Why do we have to lose all those individual commits to get that squashed commit? The answer: You don't need to.
