File a bug with the patch attached: http://wiki.gnucash.org/wiki/Git#Patches

They're maintained enough to keep them compiling by the core team. They're not
really part of our development plan, they're mostly just there.

Unfortunately Python isn't a very good built-in scripting language, and supporting
it on Mac and Windows is a serious PITA. Guile is better, except the number of
Scheme programmers loose in the world is pretty small. For the foreseeable future
I'd expect that any code accepted into GnuCash itself will have to be C/C++ or Scheme,
with a very strong preference for C++.

Rather than extending the current wrappers, I think we need to work out a reasonable
public API that properly hides the implementation. The current policy of "open kimono"
would be a serious constraint on further development if there was a bunch of external
code that we had to be worried about not breaking. The way some of the code flips back and
forth between C and Scheme is pretty bad already.
