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.
