I think I like this a lot if it means what I think it means. I want to make sure I understand it.
For Sirris VI, a planet in the Sanctum system, we may just have an article that says 'Sirris VI is the so-and-so planet of the Sanctum System. Here's all its details.' and not detail out the rest of the system unless it was story relevant? And then if something else in Sanctum came along, we'd make a place for it. We'd then rely on Struct to aggregate the places in the system, instead of listing out each of the planets individually. Over time, systems that see a lot of RP would likely see further development and their struct data would allow the system to grow in an organic fashion.
In other words, we put our focus into the places that are story relevant and don't worry so much about things that aren't?
