Thanks for trying to get this option stabilized. I think hex_literal_case is a good candidate for stabilization. I don't see any bugs in the backlog, and I assume that it's being used by projects out in the wild, but we should try to confirm if there's a good amount of real world usage.

Also, For consistency with other config options, Let's move all of these tests to tests/{source|target}/configs/hex_literal_case
