From the text above, It’s not clear what the supported scope is, but I interpret that it’s supported for all DNS services.

This existing standard that text is referring to, which one is it? The Github pull request (https://github.com/PowerDNS/pdns/pull/8874) in the release notes for this work doesn’t reference that either. Only IETF dns proxy search results that I found was on XPF (https://tools.ietf.org/id/draft-bellis-dnsop-xpf-02.html) which the text above says is going to be replaced...

But going back to previous work on Github, this reference comes up:

Have you or anyone else been discussing support for this with other DNS software vendors too?
If yes, was the reactions good? (Good like "we’re going to consider adopting that too” ?)
