When I mentioned not terribly common I was speaking specifically of GFCI breakers in the breaker panel box as opposed to GFCI in the receptacle. Even in a retrofit or remodel it isn't common to put GFCI in the panel box for the reasons noted. There aren't 240V receptacles widely available with GFCI so these tend to use the breakers. They should of course be added to any kitchens or bathrooms. It's cheap insurance.
