+1 As long as we get the tests running, I'm happy. This sounds like
something more acceptable for the infrastructure - at least based on the
discussions on this thread. The plan sounds good to me.

I think it's also possible to run amqp10 gate *just* for the changes
happening in the *amqp* package but it's probably worth it to just make
it non-voting and run it for every patch, as you mentioned.
