I don't see why you can't use MVCC for filesystems, since MVCC could be
regarded as a means of mixing the undo log into the data store itself,
eliminating it as a separate entity.

(As for vacuuming, do it incrementally and the data volume pretty much
doesn't matter; you just work through it bit by bit. PostgreSQL scales to
silly data volumes already...)
