brainwane, 
Really happy to share https://pip.pypa.io/en/latest/ux-research-design/ !
Back in 2020, during grant-funded work on the next-generation pip resolver, @sprblm did fascinating user experience research & design work. https://pyfound.blogspot.com/search/label/pip
They wrote several useful documents that took a while to get merged, but now live in pip's documentation! Like:
how to design a survey https://pip.pypa.io/en/latest/ux-research-design/guidance/#designing-surveys
how users think pip should react to dependency conflicts https://pip.pypa.io/en/latest/ux-research-design/research-results/override-conflicting-dependencies/
security practices https://pip.pypa.io/en/latest/ux-research-design/research-results/users-and-security/
