Perhaps this could have been made cleaner by relying on the package manager for download counts only, and then demonstrating the code execution scenario on research machines only. If you wanted to avoid actually downloading anything to the user's machine (after all, they expect a 404 in this case, not a package even be it a harmless one) you'd perhaps need the cooperation of the repo admins to a greater extent. Anyway, this is all part of why I always try to build inside a container, or at least in a virtualenv where I don't need to sudo the install.
