No, I don’t think it’s a bad/good idea to limit these … yet. I said perhaps as there have been historic discussions on that. It becomes only a pita of folks want them as they can create many accounts. So there are pros and cons on both sides. So I write a script right now, download a dictionary (like from john the ripper) and claim all known words and derivatives (within reason, but it’s 50Gb of words) and kill DNS usability etc. Then there is petnames also to be considered etc.
Other side is why not let somebody do that? I can see both sides of this, we can charge a lot per name, but what about the folk who have no or little safecoin etc. I think it needs properly discussed really.
So perhaps just means not yet set in code
