Auto ISO with exposure compensation is now on 1DX and 7DII. The days that ISO was the limiting factor are over. Now there are many scenarios where you want full control over apperture and shutter speed. In those cases having Auto ISO is really helpful to deal with changing light conditions. In older camera's the ISO was too limited to make that usefull, but that has changed. Off course to use that you want exposure compensation to work.
I think it is a shame that this feature has not been released to the 5DIII yet.

Auto ISO in M mode is no longer manual... it's just anther auto exposure mode.
As such, it needs to have Exposure Compensation... But it doesn't on many of the Canon models with Auto ISO. That's why I rarely use it. Maybe some of the newer models have EC on Auto ISO.
I also wouldn't use Auto ISO in combination with Tv, Av or P, either... That would be an auto-auto exposure mode! No telling what you might get!
Auto ISO also needs user-settable upper and lower limits... Which I believe some of the newer models have.
