You said those “features” would come to Android at some point.
However, there are obviously already many ROMs with them, and have been for years. Samsung, Huawei, etc.
So if, with “to Android”, you’d mean any custom ROM, you’d be wrong, because it already happened.
So the only logical conclusion is that you mean to all Android ROMs. Which also is wrong, because there will be ones without. And specifically those are the ones we’re actually talking about.
So no, those features will not come to the Android meant in this comment chain.
Everything runs through fully hardened/restricted systemd units, as separate user with minimal access rights for everything
You’d need to escape the software, restrictions and get root to do anything meaningful, while avoiding detection
