Consider that the pros are still finding 200-300 actions to perform each minute, given all of this supposed help for noobs. That means that the pros are able to plan and execute more complex strategies than they previously could, which is what an RTS is ultimately about. If you were to make basic tasks more complicated you would be removing depth of strategy from the game.
Edit: Also wanted to mention that APMs that high are basically the limit of human dexterity, so the goal should be to maximize a player's possible strategies given that amount of APM. Less automation of basic tasks would mean fewer possible strategies.
