Everything except Linux should have ZFS soon if not already, and ZFS 
will probably get an even better de-dup than this by the time backuppc 
changes would be finished.  I'd think the right approach would be to 
simply make the pool management optional so you could just turn it off 
if you expect the file system to handle it.
