Just a thought... 

The underlying issue appears to be that "policies" are being enacted before all the votes are in. People seem to be seeing posts on Meta and acting on them before any real agreement has been reached. 

I think that too many of our "policies" are more like social norms,  or common practices, leaving things open to interpretation and subsequent confusion. 

Personally I like the idea of a link-only flag. Failing that I would like to see some kind of final decision on the proper protocol for flagging link-only answers, **before people act on it.**
