No, it sounds like an absence of science. All we know is that we are somewhere between 'considerable room for growth' and 'undermining stability.' Frankly I don't think we have any more idea of the answer to that than we did on 23 Feb 1998 when the IAB wrote to Ira Magaziner (http://www.ietf.org/mail-archive/web/ietf/current/msg04154.html): > On the other hand, a very large increase in the total number of gTLDs > (say to thousands) would lead us into technically unknown territory. I suggest that there is some urgency in conducting a data-based study of where the limit to stability lies.
