To be honest, I can't remember another situation except for trees

A self-cleaning file cache is another a useful case.
This is true.
I believe a more general case would be "Caching".
I think it would make sense for caching in general, for when it gets
destroyed, to remove itself from the cache :)
However, I think a "weak ref" isn't really going to do all that extra
work in removing something from a cache. It's usually more than just
a reference inside a property somewhere... they are usally stored in
an array or a double linked list in the first place meaning that list
node itself needs to be removed.
