Why does openstack-dashboard depend on apache?

I deploy all my web services through nginx, and although openstack-dashboard optionally depends on the virtual httpd package which nginx can provide instead of apache it still depends on libapache2-mod-wsgi which in turn will require apache anyway. In practice I can just ignore it but ideally non-apache would not have to install apache. I consider this to be a logical packaging error.

Why not have an openstack-dashboard-apache package which adds apache to an openstack-dashboard package which won't pull any webserver dependencies? I believe debian does something like this. Or alternatively create an openstack-dashboard-only or some of the sort so current installations are not broken. A third option could be having some sort of wsgi virtual package which could be provided by uwsgi to remove the need for libapache2-mod-wsgi.
