That is a surprisingly hard problem, unless I make you adopt those users automatically when deleting their parent. Or what do I do instead?
If you're inclined to adoption you can do that manually already, by the way. You can have the same user be invited by multiple users currently, so if it is deleted in one branch of the tree it's still alive on the other.
On https://basspistol.org there is an example of that happening.
