Honestly, I do that, and I'm just now finally getting a gas range (delivery is tomorrow) after 10 years with a ceramic radiant cooktop. My old cooktop looks pretty much pristine for 10 years of use, and I definitely jiggle the pan around and flip the contents to help distribute the contents or the heat evenly (or both). Just like myths about cast iron, people are way more afraid of scratching their glass cooktop than they need to be. Most scratches are microfine and can be removed anyway using any glass cooktop cleaner, since it's essentially a polishing compound.
