While it would be nice to have the W, this is just another non-conference game vs. another non-conference, non-bcs opponent. I for one hope this matchup dies off as a yearly meeting. Every once in a while would be ok.
As a fan, I don't want to see the rivalry die. It isn't as important in the grand scheme of things anymore (for either team), but I think the rivalry transcends that.
To a degree, yes, you're right. But things that matter ultimately and eventually will trump things that don't. If these guys aren't playing rivalry week in the same conference, this falls into the "things that don't" category, unfortunately.
