I was surprised to find that the documentation is seriously out of date,
as in "doesn't describe the actual behavior of any gnuplot version since
before the start of the CVS repository".  I have now updated the 4.5
documentation a bit.

Could be done, certainly, but there is currently no code to interpret the
mouse location in terms like "on the status message".

Huh.  For me the x2y2 axes are echoed properly if they are active in the
current plot.  Tested on wxt, x11, and canvas.  It is true that I ignored
x2y2 in the very recent svg mouse-tracking code.  What terminal are you
using that fails to show them?
