From release notes:

So, this ticket is meant to reflect this PR: cockroachdb/cockroach#65633predominantly: the other bundled PRs in the linked PR are already addressed (as docs no-ops) in DOCS-[1466-1468].

Aside: it’s funny to receive this DOCS ticket, as I made this CRDB issue back in July: cockroachdb/cockroach#84401!

Anyways, the linked PR appears to have first appeared in {{v21.2}}(according to GitHub Refined). I stumbled upon https://cockroachlabs.atlassian.net/browse/DOC-4887 , which is explicitly a backport to v21.2 of the same release note description, suggesting that it might be a duplicate. I also see a reference to “supposed to make it into 21.2, but it never did” with some interesting context to cockroachdb/cockroach#83748.

Probably this should be closed in favor of https://cockroachlabs.atlassian.net/browse/DOC-4887; will revisit post-22.2 GA.
