[Glance] Status of image clone feature

Hello Glance folks, I'm wondering the development status of the image clone feature[1]. We provide multi region OpenStack cluster and Glance API is deployed in each region individually. We as a cloud operator want to clone same glance image attributes and images across all the regions using the cloning feature. I have checked the image interoperable feature[2] is available, but the feature looks for cloud users, not for cloud operators. If the development is suspended by some reason, we're happy to start talking the cloning feature. 1. https://wiki.openstack.org/wiki/Glance-image-cloning 2. https://docs.openstack.org/glance/latest/admin/interoperable-image-import.ht... thank you, Masahito
