The main issue I can think of is the risk of someone unplugging something 
drawing high current.  There could be a lot more flash and arc than people 
would expect from AC.  Also, the conversion to DC would require new switches 
that were DC rated on the appliances.

How would you put DC into the electric car?  I could see how a conversion could 
be set up for DC, but it seems it would be difficult for a commercial EV.  They 
have a way to take DC direct inputs, but only under certain specifications.
