So if Google decided to remove the sandboxing functionality in the next version of Android and just run every app under the same user id, that wouldn't reduce the security of Android devices?
Again, I'm not against adding seemingly redundant additional security layers, I'm against calling sandbox an universal cure for everything and using it to constrain the user in morally ambiguous way. Android system is also damaged because it makes users to root the device to do things which might be done without such elevation of privileges and, what's worse, violating warranty.
