If it is metallic and carrying power, it has to be grounded. That is
certainly doable, and it's done all the time. But for conduit added in
just to facilitate unknown future wiring, you don't know if any conduit
in particular will be for power or not. You would have to make sure it
is fully capable of being grounded even if you don't know if it will be
used for power or not. Non-metallic conduit eliminates this. You can
fish NM cable through, if the conduit is big enough, without having to
break into it along the way to get to a ground wire. Of course if you
do use conduit, you may find single wires are more convenient, anyway.
