depclean only removes packages that it knows for a fact are no longer needed.
This means
- not in world
- not linked to by anything
- not depended on by anything
"not in the tree" is not part of that list. If you have a package in world
that is not in the tree anymore, depclean will leave it as is. It will remove
ancient mere deps that are somehow still lying around though
