Kyzer Davis has since submitted two further revisions -01 and -02 in April and October 2021. See history in [2].
The current -02 draft is due to expire in April 2022. Presumably Kyzer Davis will try to get it discussed before then.
The GitHub repo tracking these drafts is https://github.com/uuid6/uuid6-ietf-draft/.
