The goal if possible is to run things like docker without needed to be
root or even more fun to run docker in a container, and in general
enable nested containers.

Frankly at the filesystem side we are rather far from being able to safely
mount untrusted device and I don't think we'll ever be robust enough to
tolerate e.g. user changing the disk while fs is using it. So would this be
FUSE-only thing or is someone still hoping that general purpose filesystems
will be robust enough in future?

FUSE will almost certainly be first. I've also been working with ext4,
and I would like to see that eventually supported to some degree.
