Well, I will admit that I prefer a grounding conductor in EMT. I very rarely see a job that has ANY engineer's input that doesn't require a ground, and if I were an inspector, I would obviously not require ground, but I would make it more difficult for the installer by always insisting on spot checking the tightness of connectors and couplings during rough in inspections. this would include making sure a lift was available for coupling way up high. These are the ones I see as most often left loose. Find one, fail the job. While I consider myself a conscientious worker, I know that I have accidentally left couplings loose, or only tightened a compression fitting with one wrench. I understand the arguments in the other direction and I am not implying that those who take the no ground position are wrong just that I believe installations are better off with a separated grounding wire.
