Here is no law for diving, but people complaigned when I did as open water diver nightdives to 24m depth with another open water diver.
And I was refused to do an icedive because of no AOW (but I did as open water diver icedives without that people then).
So to stop these complaints, I did the AOW course (also because I needed it to start technical diving as I already knew during my OW course that I wanted to become a technical diver). At that time I had already 55 dives. So the AOW course was not very useful anymore. Compass was no secret anymore, and I showed the instructor the 24m in a lake, because he did not know a deep divesite not to far from our homes.
BUT, I had one of the best instructors I had in my life for courses. He told me what he had to tell me about for example that nobody swims straight, you always go to left or right if you don't correct. And we tested it. He also accepted my experience and we had good conversations. So yes, it was a padi instructor, he was not interested in deep diving or technical diving, but I wanted it and he respected my dream of becoming a technical diver. Even now after 15 years, sometimes we have contact.
A lot of things can be learned the autodidactical way. Maybe sometimes harder and not for everybody, but it can.
I have also learned myself the frogkick, the backkick, shooting an SMB, etc. Learning navigation was done by a friend who was already an experienced diver: He said to me you are the leader this dive. He did not correct me when we came up on the other side of the lake and had to swim back at surface.
After that dive I never made that mistake again.
But even if the AOW course was just show what you already know, I had 5 good dives with that instructor. For me it was more a 'you are on the right way' than to learn new things. But also this can be good and make you a better diver. The instructor was more a coach like you have in other sports. Try to improve very small points and motivate people. I had for that 5 dives a great private coach.
This means, if people start to complaign about going deeper than 20m, doing a nightdive, etc as OW diver, then do the AOW course. Then people see you as a better diver, even if there has nothing changed. This is reality. And this can be a good, or maybe the best reason to do the AOW course. And then try to find a good coach for the course.
