I am the author of an Internet Draft (security.txt) that is going through a similar process to Mark Nottingham's RFC above, so I might be able to help.
The Internet Draft (ID) was presented at the DISPATCH meeting session at IETF 103 which includes some discussion at the end of the presentation: https://youtu.be/OAKv4Sc0jhM?t=1183. The "Informational" vs "Standards" track topic is actually brought up briefly here: https://youtu.be/OAKv4Sc0jhM?t=1660.
This is an "Informational" specification which means it went via the "Non-Standards Track". You can read more about this process here: https://www.ietf.org/standards/process/informational-vs-expe....

There were some discussions surrounding the ID in the ART mailing lists: https://mailarchive.ietf.org/arch/msg/art/52wxNQ4KI-Z_9tFuFL....
You can also see comments by the IESG review board here: https://datatracker.ietf.org/doc/rfc8959/ballot/.
Hope that clears up any confusion. :)
