pip to chose packages from a private index over PyPi even on name conflicts?

Question

I have set up a devpi server to host my own Python modules. I would like to use pip to install them and for pip to install in preference my modules, not those in PyPi.

So far, I have this:

[global]
timeout = 60
index-url = http://devpi.example.org/root/public/+simple/
trusted-host = devpi.example.org
extra-index-url = http://devpi.example.org/root/pypi/+simple/

Which works fine as long as there is no name conflict. If there is, the highest version wins which is not what I want.

I really do not wish to register empty projects on PyPi just to have the names reserved.

Is there any way to get what I want?

Modified my ~/.config/pip/pip.conf like so:

[global]
timeout = 60
trusted-host = devpi.example.org
index-url = http://devpi.example.org/root/public/+simple/

and made sure that the /root/public inherited from /root/pypi like so:

devpi use http://devpi.example.org/
devpi use http://devpi.example.org/root/public --set-cfg
devpi login root --password="MyS3kre7Pwd"
devpi index /root/public bases=root/pypi  # ← vital command.

Running:

devpi list mead --all   

gives me what I wanted:
