Yes, the starters are designed differently. Engine oil really isn't going to have enough time to leave bearing surfaces and the valve train in any significant way. First start of an engine after hours of sitting is where lack of oil is a concern. Priming the fuel pump is for short crank time and start reliability, not reducing engine wear.

That's good to know. You learn so many things by rote; rarely, it seems, do you learn the reasons behind them all. Thanks.

My cynical side wants to think the start/stop is a planned obsolescence 'feature,' but obviously I don't really know for sure.
It's an attempt at squeezing the tiny last bit of fuel mileage out in the standardised tests, and they obviously don't care if it wears things out faster...
I recently replaced my starter motor ('09 though, so I definitely don't have the feature,) so I'd be wary of that, but don't they fit longer-durability starter motors in those cars?
Actually, come to think of it, (please correct me if I'm wrong) they probably keep the fuel pump primed while 'on' but at a stop, but I'd be concerned about the lack of oil at engine start. I always was told to turn the key to on, wait for the ~2 seconds for the fuel pump to prime and after you start the engine, and let it run a bit before starting to drive.
