I want this feature precisely /because/ it interferes with packet filtering.
I sleep better knowing that my packet filters are bound to specific interfaces (with default DENY everywhere). I like to know that I can ssh in via the second card on my DB servers, without worrying about them accepting other traffic (or performance-vital traffic going over a cheap backup card).
