> This PEP is a step in the right direction: we don't want people that don't know what they are doing (which is a lot of python users, since it's a popular language among non developers) to install something outside of a venv.

And even more "just someone that wants to install python app"

> So the PEP is willing to break backward compatibility for pip to say "nope, you are not in a venv, you can't install a package" by default, and give instructions on how to do so to the user.

I'd like if the default was just "create venv for user with default name and put it there".

So the above case of "user that just wants to install app" just works, and the crap pip spews is nicely contained.
