I don't think they should do that, for different reasons. For example, lots of projects have more than one license, but GitHub seems to list only one. Incorrect information is worse than no information. Besides current implementation only seems to pay attention to most popular licenses (?)... arguably CERN Open Hardware Licence is not amongst the most popular, but for some reason I was expecting GH to detect that one ;) So again: incomplete information. Perhaps asking the repo owner to manually specify the licence could be an option, but if the repo owner cares about licences, I'm sure that information is available already.
