Review comment:
To be honest, I'm more inclined to get rid of this requirement. It seems
a little arbitrary that we require the inter-broker listener for envelope
requests only. If a principal has CLUSTER_ACTION, I think the damage they can
do already is virtually unlimited.
@abbccdda What do you think? Do we have a strong reason for this?
