It's a feature that we have to be very cautious about. The EA builds 
exposed a prototype API for a long time but there wasn't much feedback. 
Definitely not enough usage to help decide what hooks to expose. The API 
(not the implementation support)  was pulled when preparing the proposal 
for the main line (JEP 425). There is interest in some areas to explore 
the topic again, just nothing definite (no JEP) at this time.
