There are nine questions tagged reference. It has no tag wiki. Browsing the list of questions, it’s not clear to me what its intended use is.
Some of the questions appear to be seeking references for something. But most good answers on the site should include references anyway, so I’m not sure how the reference tag would help.
Do we need this tag? If so, what should its usage guidance be? I’m not suggesting that we make any effort to re-tag questions that should or shouldn’t have the tag, but if we keep the tag, then I think it should have a tag wiki excerpt to help with its usage.
Edit: It’s been a week, and it looks like no one is especially interested in keeping the tag. Should we remove it?
