Jeff,

This was an amazing article. After reviewing the previous concept, my only question is "why didn't they put it into place?"

I think this would gain a phenomenal amount of traction in the present WP community.

Anything that provides a user with more options to utilize more resources without having to rely upon shortcodes, could be nothing short of amazing.

I would love to see this concept come back onto the plate for the next release of WP.
