My thoughts on the pip side has basically always been that pip should
either:

1) Just always default to —user and add a —system or similar flag, this
    is super easy to change but is a backwards incompatible change and
    would need to go through a deprecation window.
2) Switch to —user based on if the user has permission to write to the
    site-packages or not.
