So it hasn't! Silly me, I was fooled by it being documented in the
manual.

I think that Andrew's answering a related question: for debuggers which
allow entry of console commands, the interface needs a way to update
its windows when the user types "up". Since you're just interested in
MI at the moment, I suspect that filling in -stack-info-frame is the
way to go.

I'm not sure whether -stack-select-frame should have output or not.
