I wonder if the problem with that type of device being above the hob means
that the trigger mechanism it will become very degraded over a short
period of time with a mix of steam and atomised grease from normal
cooking. Both will carry the dust from the atmosphere and deposit it on
the fire supression device. Consider how dirty the grease filter in an
extractor hob can get.

Furthermore once the flame reaches the bottom of the extractor hob will
not the grease filter also catch fire?

Yeah, there's a reason it never took off and became standard equipment.

Even with a proper electronic flame sensor, there are situations where
a full flame isnt a big deal when you have a lid that can put the flame
out with a lot less mess than that would produce. If you do still do
chips in something on the stove, a good lid for it makes more sense,
but doesnt help with the coming home from the pub ****ed, feeling
hungry, start heating the fat for frying the chips and going to sleep.

But that last is trivial to fix with a decent modern air fryer which
isnt a problem if you go to sleep and the thing beeping when
the chips are ready to eat doesnt wake you.
