Actually, no. You can't rely on having it anyway, because it is currently missing entirely, thus in all previous releases, it's missing. Code needs to check if that flag is available and only use it if so. If it suddenly goes away again, nothing will break. It's even possible to mix code compiled with that flag with code compiled without it.
