As Mo has implemented, -stack-info-frame would return the very same
information as -stack-info-depth. I always thought that -stack-info-frame
would give information about the current (or given) frame, i.e., saved pc,
saved registers, etc.

As for "up"/"down"/"frame" commands to the console, I have already
implemented a notification event on the "mi branch".
