It would be nice to see example output, and a description of why this
output was chosen: what was included, what was omitted, why it was
presented this way, what units were chosen for displaying the stats and
why. Will the things which are being displayed still be relevant (or
even available) 10 years from now. etcetera.
And the interface should be documented at some point. Doing it now
will help with the review of the proposed interface.
Because this stuff is forever and we have to get it right.
