Google's policies are actually mostly open too, so you don't have to guess :) (they are linked from the open source page). They are now a bit out of date, a few things have been simplified/relaxed (generally, the goal is as little process as possible). Then again, people also like to super-duper parse the words in the docs, which are not really written to be parsed that way.
