However, as I mentioned in my other email, we explicitly enable it back in CoCalc by patching the Sage install. This leads to probably one bug report a month, if that (so yes, it's endless, but very easy to manage), and I'm not sure those are even Sage related, since the same problem can happen with any Python install. We make bug reports very, very easy for users to create (it's 2 clicks), and there is a lot [1] of usage of Sage on CoCalc. The main thing that makes explicitly enabling this pip functionality a good idea for cocalc is that cocalc projects are clean Docker containers, and people use them for specific purposes. Also support is stupid easy due to it being a web application. So the problem you mention with random trash goes away *for us*. I think the best solution for the official Sage distribution is to provide an *option* for systems admins installing Sage to all or not allow user pip installs. Probably the default should be "no", but there should be a documented supported way of changing the behavior to "yes". I don't like having to patch sage just because of this, but I do, and *definitely* will continue to do so, because the reasoning for removing this functionality does not apply to my use case.
