Doesn't Android use SELinux in some shape/form now?

Yes. I posted an interesting technical article I found about it on here recently: https://ge0n0sis.github.io/posts/2015/12/exploring-androids-...

[Edit] this is specifically about the SELinux Kernel policy in Android

Android can get away with it, as it basically is what SELinux was made for. A device in "hostile territory" where even the user can be the "attacker".
