It's probably safe to pretend it doesn't exist now. We have a better solution in EAPI5 -- packages can force their dependents to rebuild after an upgrade. It will take a while to transition the whole tree, but if you remember to complain loudly whenever a libfoo upgrade breaks something, it will happen. In the meantime, run revdep-rebuild every once in a while.
