Subcategories for checkpoint/base model

I think a filterable set of basic subcategories (like we can filter file format or trained vs. merge) like "Realistic" "Style Imitation" "Anime" "Polygon" (CG? 3D?), "Western Cartoon/Comic", "Chibi", "Ethnicity Focused" (Not sure what to call it, but plenty of models focus on making out Asians/non-Asians etc.), "landscape", "cute" and "Abstract" that can be selected (one, multiple, or negative) when searching/browsing. Post tags don't really work here since their usage is non-standardized and you can't search negative (short of blocking it account wide) or multiple for a tag easily.
