Is the expire binding going away?

@Kai it seems that expire has been brought into openHAB 3 per this Issue that has been closed.. Does something need to be enabled to turn it on? I have seen some OH3 docs but can’t find anything that talks about this. I migrated from stable to Milestone 4 → 5. Still trying to figure it all out. Does look nice though. Great Presentation over the weekend by the way! Loving how it is all coming along.
