Is this actually an adopted standard? It's not clear from the link
above whether there's anything authoritative going on or a proposal
that some people like.

I think so, from Cary's https://groups.google.com/g/generic-abi/c/satyPkuMisk/m/KwTF_U8rBAAJ
"I will add this to the ELF spec, as proposed below:".
This question isn't alone. Carlos O'Donell asked on https://sourceware.org/pipermail/libc-alpha/2022-July/141130.html
"Is there a public repo that I can use to cross-check the glibc value with the accepted ELF gABI value?"
Let me summarize the history:
Roughly since 2015 https://groups.google.com/g/generic-abi/c/IakWYdGABjQ/m/7zTiAVveBAAJ
("Heads Up: John Wolfe no longer at Xinuos Inc"), the official generic ABI website
http://www.sco.com/developers/gabi/latest/contents.html no longer gets update. (I believe the last
change was https://groups.google.com/g/generic-abi/c/dBOS1H47Q64/m/jwc9xA9o0IsJ
"Proposed gABI addition: SHF_COMPRESS").
Since https://groups.google.com/g/generic-abi/c/9OO5vhxb00Y/m/Y0WthoOcCQAJ ("Ongoing Maintenance of the gABI"),
Cary Coutant takes on the maintenance of the gABI spec.
At the moment there is no repository. If help is needed, I am happy to convert the
/developers/gabi/latest .html files to Markdown or reST.

Yes, this is officially approved. The gABI committee runs mostly on
consensus, but as a representative for Xinuos, I can offer the formal
stamp of approval.
I am under contract with Xinuos to maintain the ELF standard, and I
have converted it from raw HTML to ReStructuredText format, with the
goal of placing it into a github repository. That last part is not yet
done, but as soon as I can, I'll make an updated version of the spec
available. Until then, you'll need to reference the June 2013 version,
with various gABI discussions to serve as amendments. As another
quasi-authoritative source, the ELF include files in the binutils git
repository are kept up to date with the gABI changes, and I'm about to
commit a change there to reflect the new compression type.

i think at this point the closest to a single point of truth for
the elf spec is cary's approval mails on the generic abi list.

Can this be picked? glibc and FreeBSD have defined this for a few months now...

Ping:) Hope that https://www.openwall.com/lists/musl/2022/07/26/1
can land in the 1.2.4 release.

It's in my branch I left unpushed while I was away and not readily
available to address any problems that might have come up from those
commits. I'm back now and I'll take a quick look thru them and push
unless there's something incredibly stupid in need of fixing. Either
way this one will be included though. :-)
