I think I'm getting the point. Rather than devstack, tempest, 
openstack-manuals and horizon have stuff baked in for certain projects, 
e.g. nova, cinder, keystone, neutron, etc, every project has to plug in 
the same way, which would force all projects to experience any pain 
associated with dealing with plugging into those projects - and help 
drive making the plugin API better for everyone.
