As a nostr user, I like that I can use as many npubs as I want.
Throw-away npubs are very useful for testing.
And having different profiles/npubs for different contexts and applications is also very powerful.
Being accountless makes trivial to generate and use several npubs.
I'm guessing how this could change with a much "reduced" namespace.
Ok the other hand, what feature could be implemented in domain assignment in order to protect against bots saturing the namespace?
