Some questions:
Does it hurt anything to go ahead and put a VF in JNDI for all deployments?  
If we did bind a VF for all, would there be much of a perf hit?
If we did bind a VF for all, would finding the markers be more expensive than just creating and binding a VF?

FYI, the marker for JSF is the presence of a FacesServlet declaration.  This is complicated in Servlet 3.0 by the fact that this declaration could be in a web-fragment.xml inside WEB-INF/lib/*.jar.  However, I assume that this declaration will be available in metadata anyway, so maybe it's not so bad.
