One of the reasons mfgs tend to recommend replacement is most rire shops cannot/do not understand tire damage. It is hard to ascertain when the carcass has been damaged due to overheating.... safer to say 'we wont repair a runflat that has been driven on'
why would you drive on a runflat and ruin the tire, when a spare and a tire repair can save the tire?

Funny you should mention overheating as that was my first concern. Being an old truck driver with over a million miles crossing Donner Pass most days I take my tires and safety very seriously. One of my OCD habits during and after any trip is to actually feel the tires with the back of my hand and "taste" the temperature. While not an entirely scientific process it does allow me to know if one tire is significantly hotter than another. Running duals on truck and trailers it's not always visually apparent that one of your tires is low. The hand trick has saved me from adding to the tire carcasses along the road by discovering a hot tire and taking appropriate action.
I did the same with my X5 after arriving and found no discernible difference between the low RFT and the other 3 tires. I guess the proof will be to see if it survives as long as the other tires over time.
And why run on a RFT? Isn't that exactly the point of having RFTs? Having 3rd row seating there is no place to stow a spare. I was originally thinking about replacing the RFTs with non RFTs when they wore out but now I'm rethinking those thoughts.
Not trying to be adversarial at all Ard. I highly value your opinions on this and other BMW forums. Just sharing my personal perspective.
