I have to say that I got the exact same impression.

Assuming for a moment that it's indeed decided that JAX-RS is
Servlet.nextgen, what would that mean for the existing Servlet EG? Do
they also feel that JAX-RS should be Servlet.nextgen? And how should
we as the JSF EG respond to that? Rebase JSF from Servlet based to
being JAX-RS based?

Just some random questions that popped up ;)

Kind regards,
Arjan
