Yes, that is exactly what the rivets do, they take any peel load better than
the bond adhesive. As such they act as a stop whenever there is some failure
in the bond. Any void or separation in the bond can propagate along the
bondline until it hits a fastener.
My point regarding the installation of a pressure bulkhead using
bonding rather than fasteners is that the fasteners will keep any damage
or failure localized. A bond may have a small area of separation that
may slowly grow until the entire bulkhead fails.
