The problem is galling seizing with surface imperfections /foreign objects or maybe even friction welding with those high speed guns?

You are releasing a huge amount of energy when doing a hot pitstop -but your claim the brakes are relying on forced convection is simply not valid when the car is stationary.I would estimate the worst case scenario is the pit stop which is not working as planned ...eg the standstill is taking longer than planned and temperatures sore ...
and :Material mismatch is sometimes very surprising...but Ti is known for this .so you don´t even try without coating ,the coating will help the surface but local stress may still move the material beneath globally and expose uncoated base or dig into the other component.
As a sideline wheelnuts look just awful after a few mounting dismaounting actions ,and all teams use big gobs of monting compounds -with solid particles- to provide a non galling protection- It all is a bit fishy ,at least for me-

In fact nuts are usually easier to remove at elevated temperatures. My BMW has copper locking nuts on the exhaust. I changed them to stainless steel, and lo and behold the steel nuts fell off after a few days of driving. They just loosend up all by them selves and fell off. The studs were 8.8 steel.
What is happening is galling or ripping of the first thread when the wheel is not engaged onto the pegs and the nut is torqued before all thread is fully engaged.
This will start a self locking action and increase the friction dramatically
Correct..but it is because it is or is trying to cross thread. Higbee aside I think a coarser thread could be the answer. Perhaps that's the crux right there,,That they or the supplier changed the threading on them. Is there a mismatch...SAE vs Metric?
Also I have long wondered..
I believe the thread is carefully specified by McLaren in this case

Look at the picture...It's a standard thread.
