Well, in a sense to support undeletion *well*, you pretty much need to
design the fs with this idea in mind. I think NWFS has some smarts to
deal with undeletion internally for example (and has done for a long
time).

Much of the time for most people it just isn't required... there are
userspace solutions that work pretty well for most people most of the
time.
Undeletion doesn't help when you scribble over a file or save the
wrong version in the wrong place, so in a sense you don't really want
undeletion but RO snapshots that do COW on the underlying extents as
required. This is what WAFL provides and it works really well.
