Yeah, this kind of "registration" would be welcomed since there are constant wipes due to the beta tests.
I still think there is time to "fix" it. Devs probably still have the gang logs of previous betas, they can restore it to the former leaders. I personally would be pissed, and probably stop playing if someone my gang name, not for butthurt, simply because yes, people build websites and stuff like that around a name, now imagine, you having to use x website for an y guild, or x irc channel for y guild and yes, although you can warn everyone about a new website and irc channel, if old members decide to come back they won't have a clue.
Devs really should do something about it.
