I think this is fine, however there is a "but" coming. I believe there will be some "site" configuration which people will desire, for example whether users can or cannot invite other users to projects or can create new users. Some of these operations will need to be restricted to some set of users. So whilst I like the idea, there will be a pressure towards elements of the other model and there are some reasons for that which we should try and consider if we can. I feel I'm explaining that badly, I hope this is understandable...
