On second thoughts, I'm beginning to think this is worth it. It'd be at the opposite end of the apartment from my other zwave devices with the hub in the middle so I won't expect any of my zwave devices to go through it.

That is not how Zwave mesh works. If it wants to route through it, it will no matter where it is physically located.
