FYI I opened Allow uploading `.pyz`/zipapp files to PyPI? to discuss the idea of allowing .pyz files on PyPI. The reason I bring this is up is discoverability of pip.pyz is going to be pip-specific and thus have to be hard-coded into any CI/CD system that wants to integrate this copy of pip. For instance, if VS Code were to ship this, how do we know when there’s a new .pyz copy of pip to start shipping?
