The basic question is "Are they on the core team because they work at Google?" - If someone new joined Google, would they immediately get added to the core team, with no history of contributions? - If someone had a long history of contributions, but wasn't hired by Google, could they join the core team? Those two questions are pretty determinate on whether this is a community project or a Google project.
