I think this is just wishful thinking. resowners are backend-private,
and they are robust as long as they are managing files accessed by a
single backend. Trying to bend them into some kind of a state where
they can manage a resource shared across multiple cooperating backends
is fundamentally changing the model. What matters is not whether the
old model was any good but whether the new one is any good.
