I agree, the kinetic (physical) difference between rolling and standing start is neglible, the operational differences matter more.
(I had the recent de-icing question in my mind, which involved a 70%/30s engine runup on the runway, and limited my answer to the physical aspect only ("theoretical considerations", as opposed to practical advice). I'm sorry if that wasn't clear.)
