The one thing I think is missing is the context.
when would you have a situation where you need a unified depth pass for a
quickly moving motion blurred foreground AND a moving motion blurred
background?
In those cases you usually isolate the depth passes for the foreground and
background elements to have more range and control on individual items, and
in that case the artifacts of BG VS FG will not matter since what you are
doing happens in the object/bundle of objects in the respective layers.
There sure are situations where these issues may arise, but they seem to be
mostly exceptions since most times you have a hero in foreground on a shot
plate and only additional props or photogrammetry on the back place.
If we consider a single beauty for all the elements, or fully CGmovies
rendered in one huge go, I'll agree; but how common a situation is that?
Passes should be sensibly used to split FG and BG layers as well, and in
that case you want individual depth passes.

Given that AA should be avoided as it introduces depth errors the same goes
for any other edgeblurring proces - mb included.
I suppose the only solution to having motion blur AND DOF is the expensive
way. I'd like to be proven wrong though...
