I would like to make you aware of this RFC started by Gerard: https://www.wikidata.org/wiki/Wikidata:Requests_for_comment/Define_lists_on_...
It is interesting because in the end, what is the difference between a list, a category, and a query? Not much, really.
I'm curious to know if the approach taken with queries will be the same as the WDQ http://tools.wmflabs.org/reasonator/?&q=6573995
Items like "List of..." or "Category:" would have some use, but the development notes don't state if this is the intended path https://meta.wikimedia.org/wiki/Wikidata/Development/Queries
Any thoughts about it?
Cheers, Micru
