Here's another use case: We use the "retype" cinder function to relocate existing volumes to another storage backend. As expected, it only works for detached volumes. But since we cannot detach root volumes even from a shut down instance, we cannot retype root volumes at all. Since the majority of the affected instances only got one volume (the root volume), the retype function is basically useless.
