Usually a setup.py script just provides the options for the install
command to be run,
not extra options for a package installer like Pip.

IOW, defining where the package installer should look for
distributions should be configured
at its level, not at the distribution level, because one distribution
may be located in several
PyPI-like servers and cannot know in advance which installer will be
used for it to be installed,
and on which server it will be hosted at

So for Pip, imho you should list all your pypi servers using
--extra-index-url and leave the
distributions' setup.py alone.
