Yes. I visited that site and examined some of the partially constructed buildings, and talked to a couple of the workers.

They have videos discussing how you would add a light switch or remove one -- basically a mansonry hole saw, and matching grout to fill in.

It seemed slightly more trouble to do modifications than a cinder block wall, but the quality and strength was much higher. I went with low expectations but I was impressed.

I didn't see any walls at the stage of construction where I could see what the insulation was, whether is was expanding foam or fiberglass.
