Been in the Concrete Business most of my life. You can feel good about grinding the last design off your driveway without hurting the structure of the CONCRETE.
Make sure they keep water running on the blade that is removing your paint or else you are going to have some wildly crazy neighbors. The dust is amazing. They also should contain as much of the muck as possible that is created by the dust and water. Forget the chemical route. Trust me you'll be sorry if you go that way. Removing the layers down to the bare concrete is the best way to go before you start your new design. Best of luck.
