Debundle pyparsing

Hi,
I'd like to revisit the issue of bundling pyparsing [1],[2]. Recently I've encounter python project that did import matplotlib.pyparsing so it's getting slightly out of hand.  My question: do original point of "pyparsing API being too fluid" still stands, were your patches merged? Upstream repository seems to be quiet at the moment. Also I've been using maplotlib with pyparsing-1.5.6 without any problems 
Cheers,
Kacper
