This is kind of a rough blue-sky suggestion - it'd break lots of existing maps and might need to wait for a Mapnik 3. But, from watching a bunch of support requests fly by and checking out how I and others usually style maps, I'm starting to think that `allow-overlap: true` is the expected behavior, and what it does is not well-known when it comes to markers.

For labels, it makes sense: labels are presentational and usually non-overlapped on other maps. But for markers, people assume that Mapnik is doing clustering, because not showing data by default is unusual.

I'm unaware of other ramifications of this: maybe there are performance problems with displaying everything by default?
