Walter:
Excellent points. I completely agree. I do wonder why you call bail out, "NAUI Bailout" when NAUI is not one of the agencies that require bailout.
I don't know why either. Just always heard it called that, and I'm not personally aware of what years that it was required (if any), versus what years it was optional but recommended, etc.
I do vaguely recall someone at sometime who claimed that the NAUI version of the bailout was somehow different than other Agency's protocols. It could be that some people were getting it confused with Ditch-n-Don (D&D) and Remove-n-Recover (R&R) drills.
The 'bailout' I was referring to involves standing at the edge of the pool with ALL of your gear in hand (usually strung along the left arm) and air turned off. The diver shouts "NAUI!" as he jumps in*, settles to the bottom and gets dressed without losing control of any of the equipment. Once you get everything in place, you surface.
* - probably in part where the NAUI name label came from. The reason that the shout is present here is to force the diver to exhale, so that he has to use alternate means of clearing the regulator.
One variation deletes the "NAUI!" exhale as the diver jumps in the water. But with a big held breath, the diver may be unable to sink to start the exercise
Another variation requires the diver to tread water for five minutes after he surfaces. No buoyancy from air in the BC is allowed, obviously.
Yet another variation has this treading of water done with your hands out of the water to increase the challenge.
And I'm sure there's other variations too.

PS:
D&D: Ditch 'n Don: jump in with all your gear on and with an established air supply, swim to the bottom of the pool, take it all off, laying it in a pile and surface safely wearing no gear (note risk of lung expansion injury here). Do a breathhold surface dive back down to your gear, establish your air supply and then put it all back on. When complete, surface normally on scuba.
R&R: Remove & Recover: jump in with all your gear on and with an established air supply, swim to the bottom of the pool, take a piece off (or several pieces, up to all of your gear) while underwater and then put it (up to all) back on. When complete, surface normally on scuba.
