I'm not quite sure when this is going to be a problem for production (hashar has already been through it with beta as they run master)
But what new extensions need branching? What versions do we need to use of them? What configuration updates are needed? Do we need to have version dependent requires?
In 1.22wmf7 we're still using the 1.22wmf6 branches. The same will be the case for wmf8 if no newer branches are created (as previously occurred)/the updates are documented/notified in both config and make-wmf-branch.
It might not be an issue till 1.22wmf9 or later...
Halp?
