Wait, I thought this was an extra standalone library.  Are you saying
you want to make it so Linux will no longer compile on a build machine
that doesn't have Python installed?

If this is merely an extra developer tool ala bloat-o-meter and
checkpatch.pl then it's merely uninteresting to me.  (I myself wrote a
quick and dirty http://kernel.org/doc/make/menuconfig2html.py to
generate http://kernel.org/doc/menuconfig/x86.html and friends years
ago, and I still run it to update that once in a while.  There's not
much to it.)

But adding new prerequities to a build machine would be really annoying
for my use cases.
