It's no longer optional. Padi has officially deleted it from the books as of Q4 last year if I'm not mistaken on the date. They still have the skill of exchanging gear while BB'ing for DM, but now they require you to call it exchanging gear while sharing a single second stage regulator.
I had 10 students in my last class, 3 of which did their OW dives with a decent frog kick. It's tough to teach a decent class around here, nobody wants to take the time to learn it properly.
