Was showing multiple action bars on screen at one time scrapped?

This is a huge problem currently for a lot of keyboard/mouse users. The 2.0 screenshot does not show multiple action bars, though it does show an additional smaller bar above the main action bar.

I understand they want to allow addon development, but I think to encourage more PC users to play they really need to make multiple action bars on screen a huge priority.

Why haven't we heard anything regarding it lately, and when can we actually expect this to be implemented?

Or was this totally scrapped?
