It is also due, in part, to the way Cygwin's fhandler's work.

I agree, try submitting a patch for bash and see if it gets accepted.

This is because the executable files are memory mapped so that currently
running applications don't take up so much memory.

I disagree. Ok, some files maybe can't be deleted at the present time, but
say I want a directory in its new location now. If mv refused to act when
one or more files were locked I'd have to copy the whole directory and then
come back and delete the old directory later. What if I forget? I lose a
whole load of disk space, whereas if only one or two files are left behind
that's far more acceptable. It's better for mv to execute the user's command
as far as possible.

No.
