    # * To workaround https://github.com/edolstra/flake-compat/issues/25
    # * Make `updateMaterilized` scripts work (if filtering is done by `flake-compat`
    #   the `updateMaterilized` scripts will try to update the copy in the store).
    # * Allow more granular filtering done by the tests (the use of `cleanGit` and `cleanSourceWith`
    #   in `test/default.nix`).  If `flake-compat` copies the whole git repo, any change to the
    #   repo causes a change of input for all tests.
