There are reasons to disambiguate article titles, and reasons to disambiguate categories. But should the category system simply mimic what the articles do? I was surprised to find at a current CfD discussion (on Category:Matrices) that there are supporters of this idea, which I don't see mentioned on [[Wikipedia:Category names]].
We don't disambiguate article titles until we have to, as a general rule. It seems to me a major shift in thinking that we should not apply the same logic to categories.
