Will workspaces icon behave like old Unity in the future?

In the Mutter based Unity the workspaces icon behaved in a different, better and more efficient way. When clicking it it not only showed all workspaces, but also all opened windows at the same time. It was easier to move windows from workspace to workspace especially when using many maximized windows.

The workspaces feature in Compiz doesn't let the user see a window under a maximized window making it harder to manage windows.

It would be nice to see the old behavior make it into Natty or a future release.
