There can actually be something beneficial to doing an AOW dive that does not in itself have that much value as a dive. I now that sounds nuts, but let me explain.
In working with AOW students in Colorado, I like to have them do the altitude dive. They get the benefit of learning about altitude, but the altitude dive itself has no learning in it. Like the nitrox dive, there is nothing to do during the dive itself. With an AOW student take full advantage and work on other things. I use the first dives to assess the student and use the altitude dive to work on what I think will do the most good.
