Yes, sorry. I was slightly confused myself.
I rechecked my facts afterward, and, indeed, cmd was successful in executing a
script through file association, given the name including extension, even
though I explicitly removed the extension from PATHEXT and respawned the
shell to be absolutely sure.

The point about <Tab>'ing of course makes PATHEXT less and less appealing in
its native form.
