Not 100% related to your initial problem but...
Does it mean that you still shouldn't delete any images in Glance
until you are 100% sure that NO instances use them?
If you shouldn't ever delete an image, are there any plans to address
it in the future? Or is it a known "limitation" that people just have
to live with?
If you can delete an image used by one or more instances, how is
shelving affected or different? Should it not be affected?
