Mirantis' position is that the App Catalog was a good idea, but we agree 
with you that other application repositories like DockerHub and Quay.io 
are both more useful and more actively used.

The OpenStack App Catalog does indeed seem to unnecessarily compete with 
those application repositories, and we would support its retirement if 
that is what the community would like to do. We'll provide resources and 
help in winding anything down if needed.
