Yes... I agree with Werner in this instance. As modularity becomes a central component of the JVM and with the breadth of frameworks and HTTP based APIs, picking and choosing what goes in will become the norm. But for this pass, I guess we can keep it status quo.

However... with that said... we all really should be thinking about the entire upgrade compatibility issues and make a break to switch the paradigm at some point in the future. Its ok to start thinking about deprecating and not always having to be backward compatible with everything. Otherwise we will always have our boots stuck in the mud because we are holding on to older tech. Just my .02.

All of these can be easily added by a pure servlet vendor (ok easy is a bit of an exaggeration). Both Tomcat (with TomEE) and Resin seemed to have no problem adjusting. I bet Jetty eventually will offer a web profile set as well.

Second, except if I'm missed something on Servlet 3.1, we don't have a simple controller to build MVC web apps. With just Servlets and JSPs, we miss the controller. I remember that the JAX-RS 1.1 and Servlet 3.0 expert group talked about it, but I think nothing happened.
