If I understand the intent and the discussion so far, it seems that you could stop after "No Editorializing Article Titles." There are lots of ways to edit a title without editorializing.

The discussion makes me think that the words "editing" and "editorializing" are being treated as interchangeable, so a clarifying sentence or two may be necessary.

"Editing the title for clarity and other purposes is fine. Editing the title to express or alter an opinion is not."

And I agree with what seems to be a popular opinion that leaves actual implementation and enforcement to individual communities and their moderators.

Note: I find "moderation theory," if such a thing exists, a fascinating topic, but do not yet moderate any community, mostly because it looks like a scary job. I just try to abide by whatever community standards I find and leave communities whose standards stray too far from my own.
