// The idea here is to provide a body of ecosystem projects that
// let us very easily observe any changes to the actual resolution
// produced in the lock file.

/// We use a different exclude newer here because, at the time of
/// creating these benchmarks, the `pyproject.toml` files from the
/// projects wouldn't work with the exclude-newer value we use
/// elsewhere (which is 2024-03-25 at time of writing). So Instead of
/// bumping everything else, we just use our own here.
