Discussion:
If you try mimicking the release flow for a release on right now, it's busted: If I generate a dummy commit out of that failure, then run to see what gets generated, it's attempting to actually add the unversioned warnings back in: I was trying to write up a PR to enact something for , but this blocks the release piece for that. Which is fine, we have some time.

Running gendocs should add the unversioned warnings, unless the doc has <!-- TAG IS_VERSIONED --. Do you know if mark-new-version that tag before failing?
Ah, I think I see what might be happening. This is the post- version of Notice the newline fun.
Sorry which newline are you talking about? :)
My PR fixes that
Ah, yes, cool. It would help if you flagged functional changes along more loudly. :)
Yea, sorry about that. Have updated the PR description to highlight each fix.
