This is our history coming back to bite us. Two decades of DNS WG people insisting that adding new RRTYPEs is easy and anyone who thinks otherwise is a moron has blown our credibility even though we mostly don't say that any more. I also note the underwhelming IETF interest in my extension language proposal, while at the same time people who use the DNS have paid me to implement it.
I think we could put in a sentence or two pointing out that new RRTYPEs are often a better option, particularly if you might want to use wildcards.
i have reproduced your entire second suggestion here, because i think it's solid. rrset atomicity means you're right, and that underbar'ed labels need only be unique within an RRTYPE, and any registry of such labels can and therefore should be per-RRTYPE.
Technically, you are completely correct. But since the namespace is in effect infinite I would just as soon not have to explain to anyone why _foo for SRV means the same thing as _foo for URI but different from _foo for TXT. As we've seen it's hard enough to understand the separate second level underscore namespaces and we're stuck with them.
