This happens even though setuptools 60 isn't in Debian yet, because pip
downloads latest setuptools for pep517 installs that require setuptools
in the build-system section of pyproject.yaml, but then fails to
actually use that version fully (this is a bug in pip:
https://github.com/pypa/pip/issues/6264).
I'll explain what's going on in detail further down, but first I'll
present a simpler reproducer that illustrates why this might be a bug in
Debian's setuptools packaging as well:
$ docker run --rm -it debian:sid
# apt update
# apt install git python3-setuptools python3-pip
# cd /tmp
# git clone https://github.com/platformdirs/platformdirs
# cd platformdirs
# SETUPTOOLS_USE_DISTUTILS=local python3 setup.py install
running install

Here we are explicitly using Debian's setuptools package, just telling it
to use the embed
