Why?

If I had something like 10.10.11.0/24 connected to the wireless router
I can see adding a static route so the laptop goes directly to the
wlan default gateway instead of the ethernet default gateway (+ maybe
getting a redirect) & then to the wlan router to the destination.

But other than that.. I'm missing why you think it'd be better to
specify exactly what goes where.
