i think all of us have been squeamish about proliferation of carve-outs, 
which is one reason Jon Postel gave me when i asked him in ~1985 for a 
carve-out for .UUCP -- and while i disagreed at the time i have come 
around to his point of view on the matter.

of course i meant that each such namespace would get its own 
"sub-domain" under .alt (e.g., .GNS.ALT). according to david, these 
won't lead to a "land rush" because it would look like a "naming 
ghetto". i'm not concerned about lack of popularity, only whether we 
(IETF) have supplied some mechanism for domain style naming evolution. 
if someone later comes up with a better mechanism we can consider it. we 
need "something" and warren's .ALT draft is "something".

i think that's inevitable, and i expect to see development of a new RR 
type which can be placed at the apex of "example.com" telling some 
parameters for use of a .EXAMPLE.ALT "sub-domain". the IETF is not the 
protocol experimentation police unless some definite prediction of harm 
becomes the consensus. DNSOP in particular has an "if you want to do 
this, here is one way" rubric for its work. (see EDNS Client Subnet.)
