Provisioning is a milestone used for gating *backup* operation,
but it's important that restores be possible during the setup
process. In particular, some applications such as home apps may
be deliberately pushed for install after platform restore, but
before the end of the setup process. We need to be able to do
install-time restores of such apps.
