But, in order to use the NEMA 14-50 plug, you have to bring your EVSE to adapt 
between the outlet and the J1772 plug in the car.  I think Tom's statement 
would be true if he added "with standard equipment".  If most users have to 
bring an EVSE to use the outlet, I think that would reduce the likelihood of 
regular use.  If the EVSE is already present as part of the installation, it is 
more likely to be used since every commercial EV driver could use it without 
bringing equipment.

Of course, this also makes the installation much more expensive.  The person 
paying for the installation gets to decide how they want to do it.  Some smart, 
experienced EV drivers will have their own equipment, just in case.
