yes I think this is an important use case, it allows for example a
rather trivial and safe implementation of things like open kiosk
you may find in public places (or implement a scratch environment
allowing the kids to play without much risk for a more personal/private
use :-) !)
but is this the 'right' place to be doing this? It adds
complexity
Wouldn't it be simpler simply to make a working copy of a gold
image in known state and start the copy? -- We follow that
approach here
