Well analysed. Johnny Mac prob doesn’t give a tinkers darn about Rolex voiding the servicing. To him, perhaps, it is just a simple material thing to personalize to his envisioned specs, and have fun along the way. If no one can service it anymore, the watch prob already lived it’s lifespan to him.
He prob has some liking to the stock watch, but can see ways it can be modifed, to actualize something from his imagination.
That being said. I once handled a MAD Rolex, in DLC. It was quite lovely. Only thing is it costed 5x more than the watch unmodified.
