As for mileage, my bike's still new and only has about 500mi on it, hopefully it stays good.
What makes this hard to confirm of course is what now most big companies tout, nothing but benign BS to manage their
PR. Not only will Shimano not acknowledge an issue but only state that 9001 is a cosmetic refresh and totally unrelated to any cable issue that they never admitted to. The rumor as you say relates to change in cable entry which I just don't see. It has been 'speculated' that cable entry has been tweaked to make 9001 like 6800 which has reported fewer issues, but there still have been cable failures with 6800. Any tweak to cable entry seems like a weak argument to me. Yes they changed the little cover where the cable housing penetrates the shifter body like 6800 but I don't see how this would have any effect. Cable freying/breakage occurs right around the bend where the cable rubs on the 'cable guide' I show in the picture and it is the same part number for all three shifters, 6800, 9000 and 9001. So I am dubious about this addressing any cable failure.
Companies to lower their failure rate make 'silent' running engineering changes. They do this without notice to the buying public. For example, they could have tweaked the gauge or material properties of their new poly cables they are running and then magically cable snapping stops. More will be learned over time because eventually the public figures it out...the truth comes out because durability performance based upon a large sample size and enough cycles doesn't lie.
