The question is: Do you want to take versioning support into
the file system intendedly? FreeBSD keeps most things on a
per-file basis (ordinary files, devices, processes etc.).
Versioning can always be added as a separate solution
(using versioning systems as separate programs) that does
not make any assumptions on the file system used. As you
concluded, the file system's complexity would of course
grow with those requirements. In addition to your arguments,
just imagine how a fsck for such a file system would have
to be implemented...
