Yes, plllllease if we could stop thinking as a community that everyone 
and everything is inside the openstack wall; and that every company that 
deploys or uses openstack only uses things inside that wall (because 
they don't); companies don't IMHO care anymore (if they ever did) if a 
project is in the openstack wall or not, they care about it being useful 
and working and maintainable/sustainable.
