This will severly break BPF users, as we have a heavy reliance on `const volatile` variables being allocated to `.rodata`, which are passed to BPF verifier in Linux kernel as read-only values. This is critical for BPF Complie Once - Run Everywhere approach of writing portable BPF applications. We've been relying on this behavior for years now and changes this will break many existing BPF applications.
