This is just way too close to what they're doing with MVC for me to
greenlight, even though it would be useful for JSF. I must request that
we decline Leonardo's proposal for inclusion in JSF 2.3. If you find
yourself disagreeing with my request, imagine trying to explain to a new
user coming to Java EE 8 why we have two extremely similar ways to use
JSF pages.

Another reason for requesting to decline this is Neil's observation that
it is not compatible with portlets. I'm marking this PROVISIONALLY
CLOSED, however, I do leave the door open to an idea down below.

I'm sorry for allowing the discussion on this thread to go on so long
only to request that we close it down three months later. I admit that
is poor form.

As Hazem pointed out, this is already logged as
<https://java.net/jira/browse/SERVLET_SPEC-73> by Arjan.

As Leonardo's proposal is too much, the question is: what can we do in
the "url mapping" topic for JSF 2.3? If there are no replies, we can
safely call this closed for 2.3.
