In case folks haven't been involved in the IETF RFC process before, even though this is hosted on IETF.org this is just a ID (Internet Draft). They can be submitted by literally anyone. The tool to do so is here: https://datatracker.ietf.org/submit/

Lots of crazy things get submitted, and never looked at again. In order for drafts to stay alive they need to be updated with comments every 6 months. Sometimes they lead to things, and sometimes they don't. Usually some IETF working group has to be interested for a draft to go from a draft to an actual RFC.

You can see the status of this draft here: https://datatracker.ietf.org/submit/status/89166/

You can find a list of current drafts here: https://www.ietf.org/download/id-abstract.txt

Given the lack of comments on the draft, and the fact its not actually attached to an IETF working group, its fairly safe to say that this isn't actually going to become a real protocol anytime soon.
