Something tells me that a unique errorcode for atomicity failures will be
useful. What will change on the client(s) behavior-wise if there is a new
errorcode? I dunno. Maybe it can use the conflict resolution callback
system to prompt the user to resolve what now could be conveyed as a
conflict between their proposed revprop edit and the one that slipped in
underneath them. Error string comparison (your noted workaround) is a
non-starter -- let's not even speak of such things.

That said, it sounds like the code isn't a danger to the trunk. So the
question really becomes, "Will you (or someone you know) see this task
through to completion before 1.7 ships?" If you fully intend to do so, I
don't see a problem with merging back to trunk ASAP (and updating
roadmap.html not to point to the now-obsolete BRANCH-README).
