Which I think is wrong. The notes are material. I think they should
uplift to the body of the document so there is a permanent RFC record
of why the decison to not go to ICANN delegation was made.

No, I don't think I can demonstrate failure to converge on strong use
cases for delegation is weak consensus. If nobody comes forward with a
rock-solid reason to delegate, then I think its fair to call it 'not
delegated'

The problem is, I don't think I can, because I cannot argue strongly
FOR a TLD, because i believe the impetus for a TLD is aesthetic and
(as for homenet btw) driven by end user UI perception issues.

I believe that the behaviour here is going to drive to string
recognition inside code to switch:

Pythonic pseudocode:
    if fqdn.endswith('.alt'):
       do_non_dns_lookup(fqdn)
    else:
       gethostbyname(fqdn)

type decision. Thats what it think this document drives to. And, given
that, I think endswith('.alt') can be endswith(STUBNAME) and somewhere
else, STUBNAME='.alt.arpa' is going to work.

Actually you're probably right. the statement says explicitly "Other
names in the Special-Use Domain Names registry are intended for
exclusion from DNS resolution. An entry in the Special-Use Domain
Names Registry that does not require DNS resolution does not require
the registrant to control the relevant name in the DNS." So the
language there goes directly to BECAUSE you intend requesting no
delegation, you make the cut.

Ie, the fact you've decided consensus wasn't reached to delegated, and
therefore decide to say NOT DELEGATE is directly relevant to the
statement from the IAB, because it goes to the language which says 'if
not in the DNS, and a TLD, put it in the SUDN'

So if you continue to maintain this HAS to be a TLD, (which btw,
requires justifying) AND if you specifically require it NOT to be in
the DNS, then the IAB statement should be cited to drive to its
inclusion in the registry.

No, I'd like to back off that. If you do language to specify why it
has to be a TLD, and if you cite the IAB, I think the document will be
integral and complete.

in other words "I was wrong" but "now I'm right"
