This isn’t a problem on Linux or macOS or the other *nix clients though. We patch requests as it is today to prevent it from importing simplejson and cryptography for this reason.

Does pip use any advanced features in Requests, at least when it comes
to downloading packages (which is where the bootstrapping issue lies
AFAIU)? Because at this point it should like you may be better off with
a simple pure Python HTTP downloader.
