Frankly I have been telling the pip developers to just break this for years (see https://pip2014.com, which, much to my chagrin, still exists); `sudo pip install´ should just exit immediately with an error; to the extent that packagers need it, the only invocation that should work should be `sudo pip install --i-am-building-an-operating-system´.

I think it would be reasonable to let vendors do so by placing a
specific file into the "site-packages" (or perhaps even a pip config
file if we want to put more information in it).  Then upstream Python
doesn't need to have a say in it.
