So, leaving aside the question of whether this kind of code to support
a new feature should go in so soon before a release -- it seems to me
that the "compatibility problem" here is basically illusory.  To see
it, you'd have to be running the branch, using LFS as a module (which
is not the default configuration), then update to a newer snapshot of
the branch, then update only some of your modules, right?

So, who cares?
