No, gas stoves CONSTANTLY ooze dangerous gas. You cannot get a 100% sealed-whole-off burner on gas stoves. They just aren't made well enough (it would be crazy expensive).

In one study, 75% of the methane released from the stoves released while they were "off".

But yeah, there is this dumb trend in the EU to have filters that just filter the gas through a bit of (very quickly saturated and useless) carbon and spit it back out in the same room if you have an induction stove in order to seal the house better for EPC energy efficiency rating. It should be vented outside.
