The issue is really distinguishing the "other" branches I don't care about from the one that I do care about. With -w, I almost certainly care about the ref I'm writing, but that doesn't help for refs that are new (new branches or tags), for which I care about some other thing. Also, the failure is a bit hard to detect, I think, in that I could find I do recognize some ancient thing that's barely useful for exclusion, and miss something that should exclude almost everything but it's been updated. In any case, when things go wrong we simply send stuff the recipient already has, so it's not the end of the world. (And there's probably some clever way of dealing with it)
