That's the same for other alternative distributed name systems like DHT based naming. For example, how should the DHT be bootstrapped, should there be any universal root zones, etc etc. GNS and IPNS are both DHT based naming systems which make different choices, much like there are various blockchain based naming systems out there.

Anyway my understanding is that Bluesky uses DIDs for exactly that reason, to punt the actual naming implementation and avoid silly internet fights like this.
