Huh ?
I think you misunderstood. There is no reason to "rewrite" anything. All of the bundled scripts work fine, but only after you install Python. In all previous releases, all scripts that were released with the program worked WITHOUT any Python install.

By the way, how is that Poser morph target import/export script coming? There is a post just below of someone that could use just that.

P.S. Blender is compiled in C , not Python :)
