Yes, it's unsigned software. Several of my virtualenvs are broken on Catalina - apparently the binaries installed by my requirements.txt are not signed for use in Catalina. I had to accept an amount number of dialog boxes by hand to make that work. There have been others, too, beyond the virtualenvs, which I do not remember offhand.
