## Summary
Previously, given:
```toml
dependencies = [
"pycountry >= 22.1.10",
"setuptools >= 50.0.0; python_version>='3.12'"
]
```
We'd solve for the lowest version of setuptools (with _no_ lower-bound
constraint) in the `python_version < '3.12'` complement.
Closes https://github.com/astral-sh/uv/issues/8819.
