How’s that any different than keeping it updated while it’s in the tree? If it’s stale and someone comes along to fix it, it’ll be in the same state it was when it would’ve been removed. Stale code needs to be updated regardless of where it came from.

Code that is in the tree will get picked up by everyone who does a refactoring of an internal interface.

Code that is outside of the tree will need someone who goes through all of the refactorings manually.
