Okay, but it is not actually possible or compatible with how the tags are categorized, and I feel you should be well aware of this. If "Worldbuilding (Queen's Thief)" is approved into the tag set in the Character category, no one can tag their fic with "Worldbuilding (Queen's Thief)" in the Freeform category. It will convert to "Worldbuilding (Queen's Thief) - Freeform".

But sure, go ahead and tell users to "force" your fellow wranglers to "actually deal with" tags, because you think they're all lazy or something?
