Heating all this metal, water and air costs money.
Over the last few years, radiator manufactures have made radiators
with less metal, holding less water to be most economic.
Cast iron radiators got left behind as they absorb so much heat and
cost more to run.

Since when " left behind" any heat to the radiator is heat released to
the home. I live with radiators and no boiler pro here we have talked
to advocates getting rid of them. Your efficency is the boiler. Now in
floor radiant has the heat lower and under you.
