it is a nice concept but it won't protect against exploits limited to a single application. especially the browser.

if someone exploits your browser into revealing your passwords, or tells it to wipe clean your home directory - it's possible it will succeed.

it won't escalate outside of application's vm, but it's still a problem.

filesystem damage can be alleviated with vm mechanism or filesystem snapshots, private data leaks cannot.

it gets more interesting if you want to share a directory between two apps that are on different security level and ensure that they can exchange the files, and protect against potential data damage in case each app is compromised/unstable.
