Indeed. The system-site-packages option to the venv module is used 21 times, mostly
in python-dependencies and python-modules. Almost all are in the context of running
tests. This seems to be a rather unusual situation as I can't recall documenting an
option for tests.
For Python packages we don't document Python3/pip3 modules like wheel (in LFS),
install, pytest, or venv. Most of those are fairly obvious, but venv might not jump
out to new users.
I'm not sure what the best option is for this issue.
