[development] git main branch - how to use it, or not use it

There is a lot of discussion and ideas about git work flows right now. It will probably take some time for best practices to evolve and gain acceptance on d.o Regarding the main branch, others have said it seems pretty useless when a release (dev in particular) cannot be attached to it anyway. I think the only thing 'special' about main is that it is the default checked out branch when cloning a repository. So, what to do with it... I like the way the rules project seems to be handling it: Just have a readme on the main branch noting that all files are located on other branches and all work should be done there. (Even though this might be a carryover from the good ole CVS days.) Any other suggestions or words of wisdom?
