Yes, and that is one of the few reasons they still sell single outlet (not 
duplex) fixtures and cover plates.

I personally would never run just three wires for a 240 VAC outlet in my 
home. I always include a ground wire and a neutral wire, for a total of 
four wires dedicated to that one 240 VAC outlet. Running all four wires 
gives you more versatility. You could convert the run to supply a couple 
of 120 V circuits, you could use older 240 VAC equipment that requires 
the neutral wire (and a four conductor outlet) to run some 120 VAC loads 
inside, or you can run new UL approved equipment using just the two hots 
and a ground.

My Titan 425 and my Hercules II each have their own dedicated three 
conductor outlets and double pole breakers. Each of those circuits also 
has a neutral wire running all the way to the outlet box, with a wire 
nut on the end and nothing connected to it. If I want to use the neutral 
in the future it is already there. Neither the Titan or the Hercules use 
a neutral wire, and they and their service outlets are all safe and up 
to present day code. (The only exception would be if there is a 
prohibition against running a neutral wire and  not using it. I believe 
there are some rules about removal of abandoned wires when upgrades are 
made. )
