It's a social question. To be honest, for the vast majority of people i work with (and i've worked with a few: https://github.com/wchristian?tab=repositories ) it would be considered very strange to see feature branches as public and stone-written history. There's a common understanding that feature branches are feature branches because the creator wishes to avoid writing things in stone.

That said, if a team decides on that kind of convention, marking things as WIP is a neat feature. I've seen other people do that simply by creating feature branches as "<username>/feature_branch".
