basically we can't support them in nostr properly. we need to find a pointer from @name address to a pubkey, where should we search for pubkey based on name part? there is no centralized server! so we have to attach the server address to it as well. then it would be like: name@server.
about remembering, why not? someone using unique domains of themselves so its easy to remember or share. and someone are using famous providers, so you need to remember to name part only.
also we don't memorise x @ ids as well.
