It would be a terrible breaking change. Less active clients would have their user wonder where all the people went as nobody would reply to them anymore.

To fix this I suggest to add some "level" to kind-1 events. Root events should have a tag "l", "0" with replies omitting this or better yet setting the distance to the root so you can query all first level replies easily, too.
