That's true, but you cannot create the same route on two different
interfaces. I. e. if 169.254.0.0/16 is already routed through eth0,
trying to add it to eth1 will just fail with "RTNETLINK answers: File
exists" and the script aborts.

It might work to use different metrics for those multiple rules.
However, that would not make things much better; if you have multiple
interfaces, then it is simply not clear which one the user 'wants'.
