Actually, I think we want to keep multiple backends for aesthetic
reasons if nothing else. It will help with maintaining the separation
you mention above.

Of course, we first have to get the separation right.

(And make the BDB backend design sane; I still think that FSFS
outperforms BDB because its storage model and implementation are
designed better, not because a filesystem is "intrinsically" faster --
at least, for larger repositories, one would expect that a proper
database with indexes, etc., would scale better.)
