I find the whole discussion quite unnerving honestly.

pip install should do just that. notifying me if I have a version and an
upgrade is availalbe for *pip*, makes sense. doing anything *else* is
scary.

I expect --upgrade for upgrading things. THEN it should upgrade to the
latest version, unless I use a flag to specify otherwise.

Note -I'm talking from the "naive user" viewpoint.
