Professionals were Apples target a long time ago, but they just switched over to the mainstream and keeping a lot of professionals that was in the earlier segment. Year over year the Mac is dumbed down to protect the user from doing something stupid, but not really thinking about the people that don't want to be cushioned. It's great HW though.
You're forgetting professionals are also human. I don't consider lowering the chances or shooting yourself in the foot a negative. And if you're 'that' professional it should not be a problem to switch a few configuration options.
