for what its worth i dont think project actully have default in repect to eventlets vs wsgi
it really the installer that do have default. keystone i think is the only project that "defults" to wsgi
and that is because they delete the eventlet version if i am not miss remembering.
that said i do think that more project should consider moving to wsgi only.
eventually i would hope we could drop all eventlet depencies in openstack but i know that for several
of the agents like the nova agent that is hard to do. for the apis however wsgi provided a convent way
to drop that depency and improve performance at the same time.
