Android already support file permissions, file ownership, and multiple user accounts and groups. Just drop to a shell and look at the output of 'ls -l'. Just about every app on Android runs under its own UID.
However, that's all below the GUI. Above the GUI, there's only 1 real user account, one 'home' directory, one set of settings, etc.
All it's really missing is the GUI layer, and splitting the 'home' directory into properly segregated directories with the appropriate permissions in place.
There are several add-on packages that do this, mostly from companies looking to add 'work' and 'play' profiles to a device. Now, Google is just incorporating similar features into the OS.
