Summary:

Are any of the recommendations for client resolvers in this document
covered the IPR (https://datatracker.ietf.org/ipr/3077/) claimed for:

    https://tools.ietf.org/html/rfc8305#section-7

(which has some similar/related recommendations, especially 7.3)?

Otherwise, I think this is basically ready, with just a few random nits
noted below (and ignoring the jeremiad-esque tone about the
design/implications of the middlebox protocol nature of RFC 7050 ;-).

Major issues:

Minor issues:

Nits/editorial comments:

[ abstract ]
* 3rd para could be removed for brevity (but keep same in the intro)

[ 4.1 ]

* Consider whether to including references to 1.1, 8.8, and 9.9
  services.  I think the following might suffice:

    1.1.1.1  https://1.1.1.1
    8.8.8.8  https://developers.google.com/speed/public-dns/
    9.9.9.9  https://quad9.net/

* s/is is/it is/

[ 6 ]
I'm not sure I follow the logic about whether/why ipv4only.arpa
must not be a signed zone.  It seems to me that the concluding
paragraph beginning with 'Consequently, ...' actually lays out
the rationale in the most straightforward manner in this section.

It's a nice TL;DR, but I'm not sure how to formulate a useful
recommendation for reflowing text to better highlight this.

[ 8.1 ]
Consider referring to RFC 8499 for DNS terminology, if that improves
the descriptions of types of resolvers.
