Well, you might have multiple executable .py files in the same source tree. So then you would want to build multiple .pyz files, each of which has a different __zipmain__. I think of __zipmain__ as part of the format of the .pyz file, not part of the source tree. In particular, it specifies what module/function to run in the zipped source tree (and I imagine it will be adapted for other uses). In this model you're separating your development tree and the thing you deploy, which is not always the case in Python.
