Alternately, mostly deleting section 3 (the survey part), renaming the document and focusing on section 4 (the recommendations part) might be worthwhile, but that section is all about formatting TXT messages in a specific way and that's generally been considered anathema for DNS for oh so many reasons. So that may also not be a correct approach.
That ship sailed a long time ago with the failure of the SPF record. People use TXT records for one-off things and they're not going to stop.
I agree that the list of implementations should be deleted or summarized in an appendix.
What might be useful is a shorter recommendation section with no MUST stuff, since it's not standards track, saying something like:
If you use a TXT record, use a _prefix ond register it in the IANA prefix registry. Use a fixed descriptive initial part in the text string so you don't get faked out by wildcards. Do not add more junk to the TXT records in the domain itself.
If you use a CNAME record, use either a registered _prefix, or a pseudo-random prefix.
