Frankly this is one of the lower incidence rates, good luck getting very far past 100k without a pricey top-end on an air-cooled 911. These aren't Toyotas and never have been.

I'm pretty well-versed in the entire development history of the 911 and the other issues you bring up here but none of them compare to the IMS issue on water pampers. Pulled studs do not grenade a motor and none of your examples caused catastrophic engine failure on low mileage cars. Valve guides and top end jobs are things that don't even take the cars off the road, much less destroy them. Same with the BMW issues. We all know that all cars have issues and spotty maintainance can cause sludge issues and engine damage but this is in another category altogether. We're talking about perfectly maintained engines self-destructing with low miles due to a major design flaw. Not some part that just wears prematurely, (like valve guides). They're not analogous.
I just happened to run into my friend who is on his third engine tonight. The first one went @ 60k miles; (covered under warranty), second one @ exactly 120k, Porsche ate it and gave him a supposedly "updated" engine, he now has 140k on it and running good. This is a 2006 997S, bought new. He loves the car, other than the engines self-destructing. Both were IMS issues and both came out of nowhere with no warnings along the way.
I have a feeling that "matching numbers" is never going to be a big deal on these cars down the road.
