In theory we reserve the right to send basic.ack{multiple = true} at any 
time when in confirm mode.

In practice the use of mandatory (particularly with transient messages) 
might change internal timings inside the broker such that 
basic.ack{multiple = true} was very rare. But it could still happen.

You can't assume that.
