Hi Kever,
there are several reasons, here are the ones I can think of:
 1.- Python is a ~100MB weight dependency.
 2.- Because of (1) I don not have it installed by default.
 3.- My Linux distribution of choice defaults to python3 but
     u-boot requires 'python' to be python2.
 4.- "Shall use C language whenever possible."
     http://www.denx.de/wiki/U-Boot/DesignRequirements
 5.- It is not just a dependency on what needs to be installed
     on the host, is also a dependency on which programming
     languages u-boot's contributors need to know about.
     So, it can be considered an entry barrier.

I don not have strong feelings on this getting merged and certainly
will not get upset if it does not. It is entirely your decision.

I have submitted this patch series mostly "for your information" and
because Philipp thought that it "looks worthwhile":
