I don't know if it's quite what we're looking for, but we could inspect the category browser feature (for efficiency and load etc.) and perhaps switch it on...?

I'm working with Tim on making the CategoryTree extension fit for use on Wikipedia. It would help to make navigating categories easier - and would hopefully help to find messy bits. It does not solve the problem in principle, i'm afraid - IMHO, only a "facette classification" could, i.e. having distinct hierarchies for time, place, topic, etc.
In my dreams we would get rid of categories and have a system of meaningful relations between articles - like the semantic mediawiki project.
