This is good news.

"Said hack" was a work-around for the following bug:
   https://bugs.freedesktop.org/show_bug.cgi?id=58812
Strangely enough, the bug was not closed, but maybe it was fixed by accident
in a newer version of mesa.

Quite a few things depend on mesa:
   Building the following 130 packages would ensure 205 dependent packages are 
rebuilt
So it would be good to check whether it still builds on mips after the update
(Mark? my machine is so incredibly slow that I would prefer not to build
a big package). And maybe push it in a new core-update cycle then.

There is the following comment:
  ;; TODO: Add 'libxml2-python' for OpenGL ES 1.1 and 2.0 support
So maybe python might be needed one day, but is not needed now?
Did you try to check that the outcome is "the same" when dropping python?
There are no missing features that are more or less silently dropped when
removing python?
The mesa install page
   http://mesa3d.org/install.html
states the following:
"1. Prerequisites for building
1.1 General
    Python - Python is required. Version 2.6.4 or later should work.
    Python Mako module - Python Mako module is required. Version 0.7.3 or later 
should work.
    SCons is required for building on Windows and optional for Linux (it's an 
alternative to autoconf/automake.)"
