If, at one point, we have the number of articles per

available, can't we just exclude large categories? The rest should
work nicely with joins, subqueries, etc. It might even be fastest to
get two full lists of category members (should cache well), then do
the join in PHP.
That removes most of the utility of this feature. The utility would
be in getting things like a list of artists born in America in 1985,
which would be an intersection of all artists, all people born in
America, and all people born in 1985 -- all very large categories.
And whatever you set the number at, the performance of this method is
going to be bordering on unacceptable (by definition, since whatever
you set the number at is ipso facto the highest acceptable value).
