Well, I certainly don't maintain it, so it's ultimately not my call to make. 
It's a matter of manpower.  My impression has always been that there isn't 
enough of that to maintain the scipy.*plt family when John and his team are 
taking care of matplotlib.  And just as much as in the future we hope that the 
numerical functionality in matplotlib will migrate (gently) towards scipy, I 
think that scipy's core should equally divest itself from plotting conerns.

There's only so much that can be effectively maintained, documented and 
developed, and dividing responsibility is the first step towards a sustainable 
model.  I worry that by trying to carry *plt around, scipy hurts itself, given 
the limited human resources available, which are already stretched pretty thin.

While matplotlib may not be perfect, I'd rather see Travis' and Robert's time 
go towards working on core scipy issues, and let John and his group nibble 
away at matplotlib's remaining problems.  There is _plenty_ of work to do in 
scipy, believe me :)

But again: these are not my personal responsibility, so ultimately the call 
will be made by Travis, Robert and the other core developers.  But my vote is 
for deprecation, even if it has some negative impact on people.  I'd rather 
distribute it as a standalone package _outside_ of scipy, which can be used 
(and perhaps maintained in the future) by those who actually need it, without 
it being in the scipy core libraries.
