IMHO, it's just because no main KDE core applications uses those
bindings that explains they always have some problems and are often
delayed compared to current KDE API. When motivated developers will
ask why the X function is not available in bindings, or why it is
broken, be sure the current problems you have with binding will be
fixed. And moreover, maybe those developers will also help fixing the
As Aaron said, a Python KDE apps will have some late compared to KDE
C++ apps, but why not ? Is it so important ?
About other scripting languages, as often seen in Open Source, it's
people who code who generally decide about future improvements and
choices (we already saw this when CMake replaces first choice Scons
because of better support).
So Python is the first in the scripting language list because Guidance
exists, and because it's a cool apps suite. Other scripting languages
will be accepted only because something useful for KDE exists, not
just because some gurus come here to request the adding of their
