UUIDv7 has been taking HN by storm for years now! When is it going to become a proper standard, and when are libraries and databases and all the rest going to natively support it?

What kind of support do you expect? I'm pretty sure that absolute majority of software does not care about any particular bits in UUID, so you can use it today. If some software cared about any particular bits, just imitate UUIDv4, I mean those bits could be randomly generated as well. If you need generation procedure, write it yourself, it's easy.

IDs generation is usually private to a company scope and rarely need to be "universally unique".

It would appear to be in the final stages of standardization in the IETF: https://datatracker.ietf.org/doc/draft-ietf-uuidrev-rfc4122b...

Its been going through drafts and improvements. It's very close to being standardized, and many libraries are supporting it already, or new offerings are being added. For example I maintain the Dart UUID library, and my latest beta major release has v6, v7 and a custom v8. There is a list of them somewhere, I know I get pinged on every new draft by the authors because I am listed as a library maintainer on one of their pages.

How much does it change between drafts? Close enough to where I could use it in production?

Seeing as how its nearly done, it doesn't change much. It changed more often in the beginning, but its like on its final draft, or near final draft. I think the IETF plans to make final soon.
