OK, I can see that as a ~possibility~ in situations where critical focusing isn't required and the subject is far enough away that you can take advantage of the hyperfocal distance or DOF, and the lens is stopped down substantially, depending on just how critical you'd want or need the shot to be. I agree that all bets are off with lenses past a certain focal length (depending on camera body/format). I'll give this one to you based on the number of qualifiers in the discussion, although I still can't see any reason for doing such a thing other than to say you did it.
For example, your own tests a few years ago showed that MLU played a role in generating sharper pics, with a tpod mounted camera, only between certain shutter speeds, which were quite low - like 1/2 sec to 1/30 sec or something similar. If you're shooting at a faster shutter speed it would seem that the need for MLU is minimized or of no importance. Trying to hand hold many cameras (in this case we were talking about MF) at slower speeds introduces movement and degrades sharpness. So, what's to be gained by using MLU while hand holding a camera?
