"Don't tag for the renderer" is part of it and "look at this awesome transit map" is another part. Back to creating a specialty rendering that is smarter about sparse areas. I don't think that the smart sparse renderer is impossible. In fact, a new feature was discussed on the mapnik list this week, transformation plugins, that may be helpful. Transformation plugins allow you to analyze and transform the data before rendering, so that might just be the place to decide which place= to render at which size / logo / prominence. So if it interests you, have a go at it.
