that's an interesting perspective. But currently, those can be
snapshotted and made into new images (see [1]).
The approach you're describing appears to depend heavily on
capabilities of backend storage devices. If snapshoting is only
supported using these capabilities - would it mean deprecating these
capabilities? (or did you just not consider them?)
