During cranking, there is sub optimal lubrication so wear is not just limited to the starter. Agreed on hybrids but in that case starting off is assisted by the electric motor and the engine won't have to work very hard. That isn't the case with a non-hybrid gas or diesel engine. You are not only causing more frequent cranking but you are also loading the engine while lubrication is not optimal.
