I've been mulling this idea since Paris, trying to figure out the best way to present it.
But basically:
We want a smaller, slimmer, efficient core.
But we also want Drupal to, like, be useful.
We want contrib, at least the high-use end of contrib, to be smoother, more organized, released on time with core.
It's been suggested we have a contrib maintainer, who would have the unenviable task of managing a huge kaboodle.
