Instead, the flow that I think makes sense is "VCS -> sdist tree [-> sdist tree -> sdist tree -> ...] -> wheel", and the above model where the export filtering is only used when PKG-INFO doesn't exist yet will give us that.
I still object to conflating 'filter the files needed to build a wheel' with 'build an sdist' - these are different tasks which I would implement differently. And flit cannot do (sdist tree -> sdist tree). The options as I see them: 1. Make it the responsibility of the backend, not the frontend, to build cleanly (except for setup.py builds). Then there's no need for a hook to filter a build tree before building a wheel. 2. Define a hook to filter the files into a build tree, as a separate notion from building sdists. Thomas
