Though if we have a bunch of stuff we're still stabilising, it's always easier to do that work on master only rather than juggling it on two branches. But either way, it does mean the mailboxes-by-id branch needs to keep sitting on the side and being rebased until after 3.2 becomes its own branch.

Once we land mailboxes-by-id on master, I think there's gonna be a lot of big differences between 3.2 and master, which will make fixes-on-both a nuisance (no easy cherry-picks). So I think I've convinced myself we need to get 3.2 to a place we're happy with first, to avoid all the duplication.

Though... I suppose the same duplication happens anyway, but in the form of rebases to the mailboxes-by-id branch instead...
