I see good reasons indeed. For example when I bind a daemon on a given IP, I have sometimes good reasons to have the multihomed host discard packets coming from the 'wrong' interface. As long as the model (strong vs weak) is tunable via a sysctl (as it is already with net.inet.ip.check_interface), I think that this is the perfect behavior: I can select whatever fits best my needs in a given situation.
