What I'm suggesting is not an automatic or semi-automatic exposure. I'm running around somewhere, shooting in M as usual. At some point I want to change the depth-of-field but the exposure I chose earlier and was shooting at was already correct. So when I change the aperture to change the dof I need to compensate by changing the exposure time. So I for every click of one wheel I need to click the other wheel, too. The EV-Lock, while engaged, would automatically perform this compensating change to the second wheel. No automatic exposure, it's still all M, it sounds like you are reading too much into this feature.
