Yes, I think this code can go. It used to be here as an aide-memoire but the "noRelay" system relates to such an out-of-date version of this implementation as to be mostly meaningless. This related to a scheme to prevent a component trying to relay back to itself during its own initial transaction. It seems that the combination of the "linkCounts" system as well as the "no relay from undefined" semantic stops this from being a danger any longer.
