That will never happen unless EA sheds its stigma of being the "casual" football game. Also EA's consumer base for FIFA is way too large, and it would be financial suicide if EA made drastic changes to the FIFA gameplay engine, like removing assisted passing from the game. It can't be done. Can you imagine the outrage from the assisted fanboys if FIFA introduced a first touch game mechanic like PES does?
I wonder if anyone would actually notice? But you are most likely right. It's funny with FIFA online. I am a mostly semi to manual player and would lose games online just about everytime. A few days ago I switched everything to Auto Controls and started dominating my opposition in every stat. I didn't know I was a halfway decent until then!
It's just sad how the online experience is ruined for us players who like something other than Auto.
