I think you've hit the nail on the head.  This discussion seems to have
highlighted the inadequacy of place=* for deciding label size and
prominence, since there are so many factors that go in to those
decisions, and the factors change depending on the particular kind of
map you're trying to create.

As complicated as it sounds, I think Martin may be on the right track: a
relation (or node) containing statistics (population, area, number of
universities, number of university students, number of airports, number
of harbors, whether it's a national/state capitol, whether it's a
highway control city, whether it's a "global" city, etc.) which
renderers can plug in to a formula that will give them a score to
determine how it wants to render each label.
