An update to RFC 4122 is well underway: https://datatracker.ietf.org/doc/draft-ietf-uuidrev-rfc4122bis/
The last version (as of the time of writing this) is from 16 February 2023.

Editorial work seems to be happening here: https://github.com/ietf-wg-uuidrev/rfc4122bis
High-level updates are communicated here: uuid6/uuid6-ietf-draft#122

Among others, this updated standard introduces UUID versions 6 and 7. The Internet community seems to be excited about those. I trust that it's rather uncontroversial that at least those two should be added to Python's standard library once the standard is complete. But of course we should collect opinions about that idea here.

Prior art:

• Someone submitted a patch on Nov 28, 2021 without further discussion: Add UUIDv6 and UUIDv7 draft versions #29824
• There is https://github.com/stevesimmons/uuid7, published as https://pypi.org/project/uuid7
• There is https://github.com/oittaa/uuid6-python, published as https://pypi.org/project/uuid6
