From my own experience, I would be inclined to say "impressively little" wear. Significance is relative. I tend to keep my cars a very long time. Like 20 and 40 years. (Call me sentimental.) And I dread overhauls. They always seem to result in some sort of complication. And, at the very least, expense... no matter how long the original lasts. It's possible that a certain amount of extra warm up might be beneficial over the very long run. Or... it could be, as you say, insignificant... even in my situation.

It's an interesting topic. Actually "topics", since we have two questions. How do warm ups affect fuel economy under different use scenarios? And how do they affect wear? I was planning on scoping out the easier of the two: fuel economy, this week. But surely Car & Driver, or Consumer Reports, or *someone* with better resources has researched these things.

I just now got back from a long trip and am not too keen on a Google-hunt, sorting out all the credible wheat from the unreliable chaff. But I figured I'd mention.
