Do we have a missed opportunity with shared?

My pet peeve with shared is the RoI.
You were supposed to use it whenever something is "shared across 
threads". My problem with it is with the RoI of putting entire 
object graphs under that type constructor.

For now it seems shared!T is about being a monadic hatch for the 
adventurous, one you can bring your own meaning for.
