Conceptually, I'd like to then see a check that verifies that the property is only set for nodes whose parent also has it set, since that is how AXI defines it: A bus can wait for the ack from its child node, or it can acknowledge the write to its parent early. However, this breaks down as soon as a bus does the early ack: all its children by definition use posted writes (as seen by the CPU), even if they wait for stores that come from other masters.
