if there are enough votes then Gideon might consider in future release but atleast it is not in upcoming 1.4 release.
But this can be possible with plugin
see comment from gidgreen
Yes, it will be possible to build a badges plugin by combining an event module (which detects when certain events happen) with a content module (which can display the badges, I imagine in place of or alongside the user title). This would be quite a complex plugin which would also manage its own database table.
