No, that's a wrong way to put it.  The whole purpose of having common
interfaces is to give implementation a freedom to implement as long as
it conforms to the agreed-upon interfaces.  Exposing the
*implementation* of the interface to the extensions basically throws
away that freedom, and we are paying for that now.

So, no, it's definitely NOT worth the cost.
