FWIW some folks might not want a broker to process any messages if it
can't be sure that messages are being replicated to another data
centre. i.e. having a single broker own messages might be a concern.
Its kinda like having the failover option; where if a master dies, the
slave also can shut down too (as having 2 copies of each message in 2
data centres at all times might be a requirement).
