I seem to remember that that was discussed and the conclusion was that
it was reinventing the wheel --- you could perfectly well use ssl/ssh
compression if you needed it, and you'd want encryption too anyway
in most plausible scenarios where compression makes sense. (If the
network trip is long enough to justify compression, it's likely not
all secure.)
