Most use a beefed up starter vs. a conventional engine, but I have a feeling they've investigated engine wear and determined it's a non-issue when start/stop occurs in a warmed-up state.

Agreed but I am almost positive that different bearing composites are being used. This can also be accopmlised by allowing the engine to continue to rotate keeping oil pressure but opening the valve so the compression doesnt act as an engine brake. An electric oil pump also maintains that protective oil layer.
