For now HEAD formulae can't be upgraded by just running brew upgrade <formula> --HEAD. The only way to upgrade HEAD formula is to uninstall it and install once again or using reinstall which is almost the same thing. This is not very convenient. We don't know if it's time to upgrade formula, we don't have other versions. We don't reinstall stable formula to upgrade them and the same way we don't need to reinstall head formula to upgrade them. The outcome of the project is to provide HEAD versions and the ability to upgrade them.
