Ah, I think you've hit the nail on the head!!

https://github.com/pytest-dev/pytest/issues/11781

And then pytest looks for any __init__.py file it can find, including
in unreadable directories...

Unfortunately, changing the argument from str(tmpdir) to
f"--rootdir={tmpdir}" caused my computer to crash (CPU usage went
through the roof until the computer became unresponsive) - clearly
there's something not quite right here yet!!
