@JustinSainton This line may need to be adjusted to have only the object types we want to support on day 1.  Otherwise meta will be moved to the new tables and get out of sync.

If we are going with a "big bang" implementation at 3.9.x we can leave it.  If we want to try a smaller set of meta values that can be implemented at the next point release (my preference) I suggest we go with cart_item and customer.

Thoughts?
