> What's the story with these hidden, but documented MI functions?

This was a long time ago. My guess is that these commands were part
of the initial design, and the design got captured as a hidden part
of the documentation, but the commands themselves never got implemented.
Most of the time, it's mostly a matter of writing the code... They
usually get implemented when someone really needing the functionality
just goes ahead and implements it.
