Add people to the core team, remove people from the core team, change the process for promoting people (not expected of the trio)
Make decisions about special cases, like giving someone bpo permissions without commit permissions, or giving commit permissions but only for the docs (not expected of the trio)
Change the rules for the governance itself (not expected of the trio, unless there’s a PEP about it)
Since future trio will be chosen out of Python core developers, it will make sense for future Python core developers to possess some but not necessarily all, qualities of the trio as laid out in this PEP.
