Traditionally, gas burners didn't give off enough gas to reach
the explosive level in a house with the expected number of air
changes per hour. Cookers with a large wok or fish kettle
burner would have a flame failure detector on that large burner.
Nowadays, with new homes being air-tight, this may have changed.

Do they? I haven't looked at a new gas cooker for years, but a
change in requirements for air-tight homes could well have
caused that.
