Mark added cdi-dev to the recipients list, but I am not subscribed to
that (please don't add me, I rely on JJ to keep me up to date!), so this
may bounce there.

Also, Mark, there is no <jsr369-users at servlet-spec.java.net>.  The users
lists are re-used from JSR to JSR for each technology.  Thus, I have put
users at servlet-spec.java.net in place of the non-existent list.

Granted.  The proposal does not touch those.  Mark was just questioning
if it was worth it.  I am skeptical myself, but am responsive to
community input.

I'll trust that Antoine Sabot-Durand (ASD) will take your reservations
into account when deciding to press on with CDI-492-FobStuffToServlet or

That's a whole new thing, again for ASD to consider.  As you observe, it
doesn't belong in Servlet because JMS can also use it.
