The strategy that we are successfully pursuing is to standardize around file formats that the build tools generate and the installers and runtime can consume. For example we can convert a setuptools egg or a bdist_wininst .exe to a wheel, and in the future we will be able to convert e-mail style PKG-INFO to json. It's much easier to test whether a tool is producing correct metadata than to decide whether the API is compatible.
