Would it be useful for electric ranges to have plugs on the side?

I have an all-electric range (stove) in the kitchen. Input voltage of 240v. Self cleaning, 4 electric elements on the cooktop, etc.

What would be useful is a regular, standard electric plug on the side, so that I could easily plug in a skillet, or a can opener, or any other electric appliance that I need nearby.

Obviously the current is there (for the oven) – it seems like a step-down transformer is all that is needed, and a little wiring.

Why don’t manufacturers include receptable for people to plug into, on their ranges?
