Yes, I have pretty good understanding of how almost every internal engine component works. Cold oil is thicker, but I still don't see the problem here. Cold oil + load would still wear more than cold oil + no load... This "wear" you guys are talking about is probably negligible. What internals are you worried about wearing out by idling after a cold start? Piston rings? Cylinder walls? Bearings? All of them are going to wear more when there is higher cylinder pressure. Low cylinder pressure = minimal wear. End of story.
