There is this Meta thread: Tag-candidates for removal. During the last
three six months, it collected 8 answers with up to +12 upvotes. However, not a single action has so far been taken.
As burninating is something that can only be implemented by moderators (via contacting SE admin team), I would like to ask their opinions on how this process should work. What should be the rough criteria on when a suggestion gets "approved"?
Update (Sep 27)
I am bumping this thread, hoping to get an answer from one of the mods.
In the comments, @whuber pointed out that when a tag deletion seems appropriate, one of the first steps should be to edit the tag wiki excerpt to steer people away from using this tag. So e.g. the tag wiki excerpt for dataframe (35 questions, 12 votes for deletion) now says:
This tag is deprecated. DO NOT USE IT. Use [r] instead.
The question remains as to what to do after that. If the mods prefer that any such tag should be deleted manually like e.g.
[best-practices] recently was, I would ask them to explicitly say so.
