>It doesn't matter that the routers respond to ICMP, it matters that they generate them, and that they're addressed properly, and that intermediate routers don't drop them.

Sure. But I'm not about to sit here and name all the different reasons for folks. And since most here do not have a strong networking background running consumer grade routers at home, it seemed most applicable.
I could have used a more encompassing term like PMTU-D blackhole, but I didn't.
