If it's just an isolated one-off joke between a small number of people, it might be no big deal. But when it's done as part of the release process, I'm going to have serious questions about the people involved. Because it suggests that this kind of behavior is tolerated and normalized.

This is an excellent point. If the parties involved can be humble, honest, and committed to the general improvement, then there can be improvement.
