Monotone ATM considers file resurrection to be impossible (as do all
the other modern VCSes I can think of off-hand, though this
particular corner isn't something I'm super-familiar with
everywhere...).  What this means is that they enforce the invariant
that once a file is dead in a revision R, it is dead in all
descendents of that revision.  If you want to merge it back in from
another branch, well, firstly you have to do some work, because the
merge will just delete it, and secondly, the best you can do is to get
a drop/add pair that breaks its history across the merge.
