Any modern country with safety regulations will require a thermocouple in the loop if there is a pilot light on the appliance. The last non thermocouple appliance I saw was an industrial kitchen stove, but it had been modified for propane, and I suspect that the guy who did it ripped out the safety stuff.
Every factory appliance will gate the full gas flow behind the activation of a the thermocouple.
When you push and hold a dial or button to get a pilot lit, what you are actually doing is bypassing the thermocouple safety until it gets to temperature. If you release the “hold to light” knob too soon your pilot will go out since the thermocouple needs ~10 seconds to get to temp.
The only commercial kitchen stove I interact with on a somewhat regular basis is a miserable piece of crap. It has multiple pilot lights, some of which go out frequently and stink up half the building with unburnt fuel. I suspect that just the pilot lights consume $50-$100/month of natural gas.
Stoves seem to be somehow special in safety regulations. I guess regulators assume that they are never operated unattended, so they tend to have no real built in safety features. Both commercial and residential stoves will happily operate unlit at full power.
