Agreed.

I guess the issue for me is that I want to see either
(i) Exactly one name allocated, with no hand waving
about registries and other, similar names. In other
words, if someone later wants another
allocated-but-not-delegated name, they go through
exactly the same process as for this one, with the added
obligation of having to justify "another one" to the
community.
(ii) A subtree delegation and setup, with a registry,
but with the entries in that registry applying at the
third level (e.g., sink.bogus.arpa.) and not as
immediate subdomains of .ARPA.

I'm ok with this, but it seems to me that the document now does
two things. One is to set up the experiment (or possibly
long-term arrangement) that you describe above. Another is to
set up a registry that would make little sense unless it had
multiple names in it and a mechanism for populating that
registry. I'd like to either separate the two, move the
registry down a level in the DNS, or both.
