The response doesn’t indicate that someone checked to make sure it was in the rotation, only that someone with knowledge of the intent of the hotfix explained what the hotfix was intended to do.
“This is intended to do this” or “this appears to still be doing this” are very different than “This is still doing this” if that makes sense (lack of certainty vs. certainty).
It very much looks like someone actually needs to verify the thing is still in the rotation, because right now it doesn’t look like it.
