Thanks for the info on this! It sounds like my experience has been biased by coincidence. Ie, I've only lived in a house that was wired for gas once! (Northern VA). My childhood home (Also northern VA), both places in North Carolina, and Florida have all been heat-pump based, with no gas line. My apartment in the UK was even weirder: It had something called a "Economy 10", with an electric heater (resistance?) in a concrete slab under the floors that would run at night, then release heat slowly throughout the day.
