@Jeffro - I agree, most of that doesn't belong in core, not at all.

What core is doing (from what I can see and understand), is evolving an API for building such components as CMS plugins, themes or even applications on WP core.

I talked to a developer from Salon.com last week about their experience with WordPress, and he indicated they were delighted with how well it's working out for them.
