All of Debian's deltas from upstream pip are here: https://anonscm.debian.org/cgit/python-modules/packages/python-pip.git/tree/debian/patches We also have a somewhat more elaborate machinery to unbundle packages using a tool called dirtbike to turn installed (at build time) packages into wheels. That's a separate issue I'd be happy to talk more about. In any case, to the extend that we can upstream the more generally useful bits, or at least share behavior so users will have a similar experience on both ecosystems, I'd be happy to help represent Debian. Probably not much will change there until after the upcoming release though, since the archive is currently frozen.

Also note that `pip install` defaults to --user in Debian, and that alleviates a lot of the "well that didn't work, let me add sudo" urges. Upstream, this bug tracks that, although it's long standing without much recent progress: https://github.com/pypa/pip/issues/1668 IMHO, that's the right direction to go, and I think Donald is philosophically aligned (apologies if I'm misreading that, DS!). There are of course plenty of knock-on issues to work out, which is probably why that issue is still open. Defaulting to --user won't solve all the problems but I think it's very much a step in the right direction. Even with this, over in Debuntu-land we sometimes still see bug reports from people who were confused by importing an unexpected version of a package, and not remembering (or knowing) that some third party version outside of the archive had been installed, and /usr/local/lib does come before /usr/lib in sys.path. This lead to https://bugs.python.org/issue29546 which will be in 3.7 and should at least help in debugging such situations.
