I started out with manual everything cameras processing my own film, and I got pretty darn good a judging lighting by eye. Unless what you're trying to learn to do is become a human light meter, the "education" you're describing is pretty silly. You can accomplish the same results more quickly using the correct automatic setting and exposure compensation.
I started off with P&S cameras and before I knew the mechanics of cameras I was frustrated with the automatic exposures; once I discovered I was missing "manual mode" I never turned back.
Sure, from time to time I'll use the priority or program modes when the shot is more important than the learning experience, but after 4 years of hobbyist photography I still find myself with much to learn and I enjoy the challenge of manual exposures.
