All cooker controls should be timers.

I never want to turn on any part of the cooker for ever and ideally this should not be an option available to me when tired.

I'm with you on that. I once left the gas fireplace on for 6 weeks. Fortunately, nothing bad happened but a large gas bill.

Oh good point, cookers and heaters. Especially gas heaters.
