I think the NEC is staying out of it due to 90.2 the purpose of the NEC is practical safety, not a design manual.
Years back when they wanted to put mandatory voltage drop requirements back in the code the NEC refused so they put it in the Energy code, which is now adopted in most states.
Here in the rural pacific north west we never had much other than propane, nat gas just in larger towns.
The free market is eliminating propane on its own.
With all the rate increases in propane plus hidden fees in propane delivery, tank rental etc, people are switching to heat pumps and electric ranges without the government lifting a finger, but here we have cheap hydro power.
