The thing anyone taking a course like that would have to consider is what happens after the course. I remember when I took my OW, it was at a resort. I also took it very seriously. There were only two students in the class and our instructor was German...and quite rigid. I thought that was good.
But after finishing the course and the 5 required dives, I did a couple more dives before leaving the resort. It was an eye opening experience. Suddenly there was no one checking everthing I did. I had to make sure all my equipment was okay, I even had to go in the back and select my own BCD. That may not sound like a lot, but after only 5 dives, I suddenly realized how much I clearly did not know.
My first post certification dives (after leaving the resort) were in Florida. I booked on a day boat, and we headed out. It was a drift dive, with a lot of very experienced divers. I can tell you, the dives went well...but I can't imagine what it would have been like if I had only one or two dives under my belt because I had taken fast course.
If anything, I believe the overall requirements for OW should be increased, not decreased. Personally, I take responsibility for my own dives, but I fear a lot of divers don't.
