I poked around and agree with you that there isn't much other than A
and AAAA signed glue-ish records. There's a few SRV records. I don't
think any TLD other than .biz has CNAMEs. There are a lot of MX in
.NAME which is a rather peculiar TLD.

But as I said in November, there is a lot of signed glue, it is not going away,
and this draft does not match reality.  Nothing has changed and I don't see any
reason to waste more time with it.

R's,
