We should not remove that policy, and here is why:

The rule is always used, just not in the sense you're thinking about. Information learned from the sneak peeks and promos is never added to our articles before the episode airs. This is particularly necessary because OUaT episodes tend to give false information early on, and then reveal the truth in the second half of the episode. Promotional material often involves these untrue facts. This includes but is not limited to: multiple instances of glamour spells, flashbacks that seem to be present day or vice-versa and assumed deaths.

Promos and Sneak Peeks are not canon, and it needs to stay that way.

What you're talking about is quite different. For the episodes' cast list, I've edited the intro sentence before you made this suggestion, to make it point out that it is unofficial and open to changes and updates. Clarifying this, there's no harm in keeping that.

My suggestion is to reword that part of the policies, to clarify what is and what isn't acceptable to add.

For the record, the fact that some staff members break a policy does NOT invalidate that policy. Otherwise, you could also argue that we need to remove the "respect for others" every time a staff member is disrespectful.
