The flag is placed together with pointer authentication flags since they serve the same security purpose of protecting against attacks on control flow. The flag is not ABI-affecting and might be enabled separately if needed, but it's also intended to be enabled as part of pauth-enabled environments (e.g. pauthtest). See also codegen implementation #97666.
