License Proliferation

I've been following the discussions about license proliferation that have been going on the past few weeks.
I'm really glad that they are bringing up all those issues now because they are very closely related to the subject of my master's dissertation and it will surely enrich my research.
But one thought that crossed my mind today was that everyone participating in that discussion knows somehow what licenses should be recommended. But if they just say "ok, here are the licenses" people will complain that they just made that up. So what they are doing is a methodology to choose licenses, and apparently this they can just make up, expecting much less complains.
