The system defaults are whatever the user has configured at a machine level (by editing the registry, by hand or by tool (including policies)). I doubt many users have configured them by hand. There may well be tools that do it for them. Anyway, after some checking i realized #3 can't be implemented anyway in the backend, since guc won't let us know early enough. So that's out. Thus, let's go with #2.
