It's also related to this open issue, so possibly we could kill two
birds with one stone (although I guess that would still leave the
problem of what to do in the back branches).

That seems wishy-washy. If we're going to have any chance of getting
these patches in, we have to give the patch authors good feedback
early in the CommitFest so that they have time to make the necessary
revisions before the end of the CommitFest. If we think we can swing
it, I'm happy to handle these patches in the normal way; I'm also
happy to say we'll review them all but not commit them for fear of
destabilizing the tree; or we can punt them altogether. We can also
pick and choose. But saying we're going to postpone dealing with them
doesn't seem to me to solve anything.
I also think that postponement is not going to buy us very much time
anyway. Most of them are pretty small.
If SR is in, does that militate toward bumping the patches (because
now we have more potential bugs to fix) or against it (because now you
don't have to help make it committable)?
