It was used when we only supported subnet routers on linux and would nil out the SubnetRoutes slice as no other router worked with it, but now we support subnet routers on ~all platforms. The field it was setting to nil is now only used for network logging and nowhere else, so keep the field but drop the SubnetRouterWrapper as it's not useful.
