I have never been very excited about your ALT proposal. However, I don't think it will do any harm beyond thwarting any secret plans anybody might have to apply for a string in a future round of gTLD applications that is ALT or is confusingly similar to it.

I do have my doubts as to whether reservation of ALT as proposed will actually help with the problem it ostensibly seeks to solve.

People have always been able to anchor their non-DNS naming schemes to domain names they control in the DNS as a way to avoid collisions, and nobody has seemed to think that's a good idea. Is it more likely that someone would anchor their ARTICHOKE alternative naming scheme under ARTICHOKE.ALT than it was for them to use (say) ARTICHOKE.NZ or ARTICHOKE.GLOBAL or something? Even within the IETF we struggled slightly to convince people to use HOME.ARPA instead of HOME, right?

Q: has anybody ever indicated that they would use ALT to anchor a non-DNS but domain-like naming scheme?
A: not so far as we know.

However, I appreciate we can't tell whether it will solve any problem until we try it. I stand ready to eat some kind of at least passably-edible hat if called to do so five years from now.
