IMHO, the work should be done for that. We discussed of this during
packager meeting
( http://meetbot.mageia.org/mageia-dev/2011/mageia-dev.2011-01-26-20.03.html ), but no patch were written. I estimated the work to 1 day for someone who know perl and can read perl-URPM documentation, and packagekit one.
