The discussions around 'pinning' support for disconnected AFS came up on doing exactly this as the only real option for implementing pinned vnodes on clients without XCB. Significant concerns around about server load and callback storms mean that it has not yet been implemented. However, I don't think the idea that a client might respond to a callback break with a fetch status is that far fetched.
