Yes. I think the main category problem is that fanworks and fan activities are not broken up by fandom. The whole category approach so far seemed to have been to minimize the number of categories with no fandom categories, and now with this proposal that only some big franchises are supposed to get a fandom category that is the same problem. As if the goal was to avoid categories. I'm similarly perplexed actually why we only have a single category for fan but not one for "fanartists", "fanwriters", "vidders", instead you end up tagging people with the category "Video" out of desperation because there is no way to mark them as people who make videos.
