It technically does not matter today. Sure the SOTA fabs only exist in a few places, but it’s not like a 2010/2015/2020 era chip is unusable trash. All of which are more geographically distributed.

For any critical workload a chip is considered trash after 5-7 years. They still run , of course, but increased incidents on platforms that are supposed to be 99.99 are hard to work with. Now if you mean there’s unused stock of those , that would maybe work, but I am not aware of significant unused stocks.
