There is a tangle between interface and routing info.  An interface can be 
asymmetric.  But the asymmetry can also be one or more hops away.  You might 
be able to catch that case based on IP address.

This could turn into a bottomless pit.  There could be a router on the far 
end of an asymmetric link that routes to many CIDR blocks.
