Perhaps you should set your d-scan to show towers. Low is full of active towers on moons, both extracting from valuable moons and running reaction chains.
They are there on all the money moons right now, and yes this change will do what you want, since they have to bring miners to fill up local, offer you targets and show their presence for hours at a time, not a cyno alt, jf onto docking ring, 10 minutes with a local hauling ship and then jf gone, for another 30 days. (all the extra effort of which is probably going to just free up moons for locals).
You could go survey a low region right now if you wanted to see where it stands currently.
