I've given it more consideration and I believe we should classify brows until as many objective *_eyebrows tags as exist and then create a pool for appealing ones as suggested earlier. It's too much of a subjective and dilution-prone idea for a tag and would require significant overhaul. As it stands eyebrows is totally deluded and serves no basis for creating such a pool, so I don't object to a nuke. I will cultivate a fav list of brows I like and share it later if I think it would make a good basis for a pool
