Create a separate post for discussion instead
Policy posts are for documentation of what the policy is. Opinions on said policy, positive or negative, do not belong on the policy itself.
Questions that only exist for documenting policy are a weird use of a Q&A engine, sure, but Meta has always been a weird use of a Q&A engine. We make do with what we have, and it mostly works.
A policy post that contains both documentation of the current policy and opinions on (potentially outdated!) versions of the policy is just a huge mess that doesn't help anyone. This is especially true where the policy is especially unpopular, resulting in the actual policy being at the bottom of the page, below all the answers responding to it. It also ensures that discussion on an unpopular policy gets buried off the front page, as the question promptly gets downvoted into oblivion.
We've regularly removed attempts to litigate policy from Meta Stack Overflow posts describing policy, used comment locks, etc., and instead told people to post a discussion post if they want to discuss policy. Such a post can also be upvoted to ensure that the important discussion is visible to the community so that they are able to voice their opinions.
TL;DR: Staff should ideally post a discussion post alongside a new policy. If they don't, someone should make one.
