What's this talk about the $10,000 cost of diversions as if it is a factor in your decision in how safely you will continue. Surely you don't mean that?
Considering the commercial implications of decisions that you make or may have to make goes with the territory of being a commercial pilot, it has always been so and always will be.
PS. If you can divert a long haul aircraft for $10,000 you are doing pretty well, you could easily add another zero in some circumstances.
