you are right in saying that most of PADI's problem is ommission.
a few things to unlearn are:
vertical bodyposition
ascent procedure
turning tankvalve back 1/2 or 1 turn
be back at boat with 500 psi nonsense
ankle weights
using suit for bouyancy
'having to much weight is ok'
Ok, first, I'll admit that I don't have a manual in front of me, but I can't remember being taught any of these things.
However, here's a few comments:
Vertical body position: True, the whole concept of streamlined trim is merely touched upon in the OW book, and usually not bothered with in the water. I'd still call this omission.
Ascent procedure: referring to what "problem"?
Turning back the valve 1/4 to 1/2 I think is what they recommend, and I'd have to concur. (At least back off of "locked" open.)
500 psi @ boat: not taught as a rule, but I believe that it's the standard for conducting classes. Problem?
Ankle wieghts: Not discussed in OW class that I'm aware of.
Suit for bouyancy: I assume you mean in the drysuit specialty class... haven't taken it, so don't know. But it seems there are two schools of thught on this prcatice, both with seasoned experts behind them.
Too much weight is ok: Well, within reason, it certainly is "OK", as a little too much is much better than a little to little, IMO. However, they very carefully teach how to properly weight. However, many instructors prefer to sink the student to the platform so they don't go floating away. So this is a human problem, not a PADI curriculum problem.
Right?
