I agree. With increasing support for 1.0, going back to add 0-10 support 
doesn't make much sense. For interoperability with AMQP, 1.0 is where it 
will happen.

Most clients that support 0-10 now also support 1.0 through the same 
API, so switching may be possible. You can also do bridging between 0-10 
and 1.0 using e.g. qpidd. I have had success with (admittedly quite 
simple) tests between qpid::messaging, qpidd and RabbitMQ over 1.0.
