Would you mind clarifying where the "two remaining" comes from? I can still find more https://docs.sqlalchemy.org/en/14 references in the main branch. Thanks!

Yeah this PR is fine, but it does not fix #69164 since there are still many remaining. The fixed occurences are not docs to begin with (they are in-code comments).

[levgiorg]

Thanks for the review @uranusjr! Let me search for the remaining en/14 links and update those too.
