The two use cases which I am aware of are:
* You accidently checked in sensitive information and need it
* You accidentally checked in large chunks of (unused) information
(perhaps some .iso was somehow included), which is sitting there
bloating your repository for no good reason.
FreeBSD can't use a VCS which does not have any sort of obliterate
support because these two use cases have occured already in the past,
and we are pretty confident they will happen again. We are humans,
after all, and fallible beings at that :)
The two major VCS systems used today in FreeBSD work are CVS and
Perforce. CVS doesn't really have `obliterate support', but with a bit
of manual repo-surgery things can look "as if" it had. Perforce has a
special command to obliterate files.
