Gas valves and igniters don't even need much power. They could put a battery in there so it could be used when the power is out. My propane fireplace runs for years on 4 AA batteries and that's powering the receiver for the remote too.
The burner valves operate mechanically. It has an additional shutoff valve that closes when there's no electrical power. A battery backup for the igniters would be a great feature though - a Li-ion battery stored at half charge would last pretty much forever.
Heat makes lithium ion batteries fail much quicker. A non rechargeable lithium AA would last a long time and they don't leak like alkaline batteries.
Heat is bad, but the battery could be positioned below the oven. Disposable would be cheaper.
