   PEP 103 talks about consequences and price a lot, perhaps too much. :-)

   Good question! In git, when you assign an upstream remote-tracking
branch (manually or automatically when cloning an existing repo) you're
essentially declare that remote the public repository on a per-branch
basis.

   But certainly there are distributed development scenarios where there
are no upstream remote-tracking branches at all. For example, I develop
SQLObject using two private clones (clean backup repo and dirty working
repo) and three public clones at Gitlab, GutHub and SourceForge. They
are all equal, none of them is the upstream. I don't even have
``origin`` remote - the origin was in Subversion.
