teamwork tag

How useful is this tag, really? It seems to me that it's a super old tag that was used in the early days in place of tags like multiple_fellatio, multiple_paizuri and all the threesome tags, which didn't exist back then. Most of the tagged pics are porn from over 10 years ago, and the few that aren't are very broad in their definition of teamwork.
For explicit pictures it's pretty much obsolete, but for safe pictures it's potentially underused.

In the erotic sense, I see no point, because it duplicates other tags with many characters.
In the case of joint participation in the case, it is necessary to check for the presence of a similar tag.
The current description of the tag made it useless, but there are posts with a different meaning: teamwork rating:s (above 3 year).
Probably the change to the wiki (by evazion) in 2014 without any clarifications destroyed the original meaning of the tag.

If you follow the tag history, even back in 2014 it was mostly for group sex acts.

I'd say the tag is mostly useless because it doesn't make sense to include rating:e and rating:s posts together under this tag.

I don't think we have a similar concept under rating:s. Why don't we just purge the posts for which there's a better rating:e tag from this and update the wiki from there with "characters exhibiting cooperation (in a non-sexual context)" or something along those lines?
