Gas-fired furnaces or heaters should not have an impact because the only 
electrical requirement is to fire up the pilot light.

But fully-electric heating has a much higher impact on energy sources 
(heat pumps being the least).

I believe typical electric central furnaces are anywhere between 10kW - 
15kW systems. Would a standard 4kVA - 8kVA generator for average Jane 
cut it? Not sure.

Then again, I live in a more forgiving climate, so I have a very limited 
need to understand this better.

But I can understand why the code has not caught up to this yet, and 
insists on hard-wiring the devices... because the majority of home and 
buildings will still be using all-electric equipment that require plenty 
of energy, where things can go wrong if you allow Jane to just run her 
suicide cord any way she may like. Yes, there may be more folk moving 
over to other energy sources that eliminate or reduce the need for 
electricity, but the code has to cater for the wider demographic.
