I'm not sure if this is expected behavior, a pdm problem, a sign we're holding pdm wrong, or a sign I'm holding dream2nix wrong--but I noticed that new/removed/renamed groups added to my pyproject.toml under [tool.pdm.dev-dependencies] don't get updated in the [metadata] section at the top of pdm.lock unless I remove the file before running nix run .#blah.lock.
