Also "CSS2", "SVG" or WhatWG specs could get their own filter, as @Zefling suggested there: https://github.com/LeaVerou/css3test/pull/212#issuecomment-1006495331 And we could put the rest in a "Others" category in order to make all the categories be a partition of the set of specs.
I generally agree with that. (Note that we already have a filter for CSS 2.)
