I find it funny that the NEC seems to cover every detail you could
think of, but not this one.

well it does matter in the sense that many cords and wall warts seem
to hang better with the ground pin down....but many commercial
buildings seem to have the ground pin up...

Except that, as someone else pointed out, almost all wall warts have 2
prongs and no ground pin.

However, some (for no apparent reason) have POLARIZED plugs. That has
the same effect as having a ground pin, for limiting the ways they can
be turned.
