I'm a bit confused on when/if the themes tag should be used. For example, take the following question:
While looking through available tags, it seems as though the themes tag is there to address concerns with specific themes (in this case, the question asks about Bartik, but could also be applied to the small handful of core themes that exist).
However, I noticed it was soon removed, which is totally fine--I'm just looking for some guidance and/or documentation so I don't make a similar mistake again. I noticed some discussion on merging similar tags, though nothing on when this tag should or shouldn't be used beyond what is already in the tag description. If the tag isn't already deprecated, what are the best practices regarding use of this tag?
