Does restoring a volume online make any logical sense? Generally operating systems don't like it when a mounted volume changes contents, and a restore, being a slow sequential write is likely to be even worse. Since you have to unmount anyway, attaching a new volume should not be an issue.
Just because a feature is technically possible doesn't mean it is a good idea, particularly when the use of that feature under normal circumstances causes data corruption. We have plenty of code paths in cinder already that are hard to exercise fully and buggy (e.g migration) without adding more.
