Great. I would just like to remind that Tom said:

so that the selector function could be moved to contrib/ltree, which is
its natural place.

It could also be noted that a similar feature could be useful outside
ltree: I guess there are plenty of cases when scanning statistics would
give a better result than using a constant selectivity.
