Hello,
some analog EOS cameras like f.e. the old EOS 5 featured DEP mode (not the almost useless A-DEP of later models). You could use an AF field to focus the far point on first half shutter press, then focus the near point on next half shutter press, then point to the desired view and press shutter to release. The camera calculated the necessary values for aperture, exposure time and focused the lens to the appropriate DOF distance.
I found this a very useful feature and never understood why Canon didn't use it in the following models or replaced it with A-DEP where it isn't possible to choose near and far point on your own.
Would this be possible in ML?

I'm afraid it's only technically possible in LiveView, with lenses that report focus distance.
(which is pretty useless, given how well autofocus works in LiveView)
Would it work with Quick AF or only with Live AF? If it worked with Quick AF this would already be a large benefit but even with Live AF it would be of some worth, especially in landscape photography, where it is not easy to estimate the DOF.
I too would love to see the original DEP shooting mode implemented. I consider it to be very useful even with Live view.
