Default env created by the installer should have option to skip setuptools

          on reflection if you're talking specifically about the environment in which poetry is installed by the installer - you could try raising a feature request in https://github.com/python-poetry/install.python-poetry.org

it seems plausible that this environment doesn't need setuptools at all, maybe the installer should always pass the --no-setuptools flag to virtualenv at environment creation

Yes, this would be great. Today we found out that we have a CVE against setuptools that we needed to upgrade. This means we need to run an additional command to upgrade the setuptools in the venv that poetry uses itself.
