There is a lot of excitement in that topic, which is always nice to see! It's good to get more eyeballs on information at all times.
Just want to provide some more context as the OP of that post did not. This document is a SEC comment letter which can be found at it's original home here: https://www.sec.gov/comments/s7-11-23/s71123.htm (letter type C)
September 11th 2023 (date this was filed) was the last day they were accepting public comments https://www.sec.gov/files/rules/proposed/2023/34-97877.pdf
so this document is just a few days shy of four months old, and from some skimming looks to me like mostly a collection of other publicly released filings / snippits / quotes. Definitely a nice collection but not necessarily indicative that the SEC is recognizing their relevancy.
