The other extreme is that, what if you are singly-homed? Then it is useless again. My point is, I would guess that if you are not single-homed (in which case this is useless), you are multi-homed, and your traffic probably isn't symmetrical. Therefore, I think this feature is of limited usefullness.
It would prevent simple spoofing, yes, but that would not eliminate the Smurf attacks since to mount a Smurf attack you need to use the victim's address as your source address, and that one *is* typically "valid" according to the criteria you mention above (?).
