No, it's not. It's not a change we can make for the default that everyone uses. If you're keen to mess up installations you control (aka ubuntu valuedadd viper) push it into a special LSM or rather a non-standard rule for it. It really doesn't matter if it's in fs/ or security/ but it's simplify not going to happen by default.
