Patch to follow based on responses. I actually noticed this the other day too, I just forgot to file a bug about it. Since the "uniqueness" of a domain is ultimately decided by the UUID, I think that editing the name should be an allowed operation, and we should just handle it. This, of course, brings up the question of what do you do if you want to change the UUID. Following the principle of least surprise, though, I would think that editing the UUID would also be allowed. If you did so, I guess it would be considered a new domain, but we should be able to handle that as well.
