No, the header doesn't have version information. Moreover I think checking for functionality is actually better than checking a random version number because it actually documents what we need. As I've already adapted the existing test below, I think we can also leave it for now. The only advantage of deleting them would be to have less lines ;-) https://codereview.appspot.com/563560043/
