Basically three reasons: - There's a lot of code to handle a variety of situations in pip, it would be much harder to extract this code and keep it up to date in a way that the "mini pip" could use it. It would also not be as battle worn as the pip code. - On top of the one time cost there is the ongoing cost. As the packaging ecosystem progresses the stdlib implementation will need to be kept up to date as well as the pip code. - We need to include a copy of pip in order to support offline installs either way. Since we have the private copy there to support offline we might as well use it to handle everything. ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
