I was going to add a [noose emoji]🤔 tag, but there's no noose emoji yet. But I found a Github issue where anyone with the time/inclination can add details to turn it into a full proposal, and the repository's owner will presumably submit it property for requested addition to the standard. If someone's fast and thorough enough, then it might become an emoji as soon as 2019. This $5-25 worth of fanart shows that there's economically important interest!
