Sounds sane to me.

To put it another way, assuming all AMQP 1.0 client libraries are equal,
all the operator cares about is that we have a driver that connect into
whatever AMQP 1.0 messaging topology they want to use.

Of course, not all client libraries will be equal, so if we don't offer
the choice of library/driver to the operator, then the onus is on us to
pick the best client library for this driver.
