Comment (by petr@…):

 Vincent, thanks!

 Looking at this again, I am just wondering if we should not keep a
 *deprecation version* of this variant for a while. This would help to
 provide a smoother upgrade path for people, who had installed with this
 variant. I'd suggest to have a console output in pre-configure, when
 people try to update with this variant active with the hint that they
 should install `py27-gdal` instead. Doing this automatically is
 unfortunately not possible due the the dependency.
