What I meant is that I am wary of putting too much policy into the kernel

reasonable to me if we keep the scope narrow. More complex policy, such as
changing multiple defaults still seems better handled by userspace.

Would adding only switchdev/switchdev_inactive for now be acceptable?
I will try to keep the code generic enough so it can be extended later if
we want.

I wanted the format to be reasonably generic, but yes, just for making
future extensions possible. I don't expect us to add anything beyond 
the switchdev flag at this point. We don't have to implement the device
matching either. Just a comment in the code how we expect the full
format to look like would be enough, for whoever needs it in the future.
