That would be possible as well. When we discussed offloading selection
we thought allowing the user to fallback to another offloading mode when
a rule or a set of rules isn't supported by a given device would be
useful, even though updating the offloading selection at runtime isn't
fully transparent for now (this would be a nice follow-up).

Thanks,
Antoine
