Actually, people could do this today:

1) dump the repository to DUMPFILE
2) run some kinda script that rewrites the sections to obliterate, producing
   (probably want to keep the same revs; just edit the contents)
3) load DUMPFILE2 into a new repository

All this is possible *today*. And our dump file format is documented in
notes/fs_dumprestore.txt. Assuming that we are good about keeping our
dump/load compatible with that, then people can start writing all kinds of
neat tools to operate on dumpfiles.
