It's a tricky balance, I think, for a "build a station in the middle of nowhere" CG.
* You need Commodities and Outfitting for the CG to take place at all. The current ruling faction brings a Black Market in with that, though you can't actually access it until Contacts is enabled.
* In the event that someone manages to get this far out without a fuel scoop, they can buy one in Outfitting, so it might as well have Refuel.
* You're going to spend more time grabbing synthesis mats than actually mining if it doesn't have Restock - especially if the CG is for core minerals and you need to refill the mining missiles.
* You need Authority Contacts to avoid what in a normal situation would be a 100 credit warning fine turning into a 11kLY detour.
* You also really need a nearby detention centre, or a slightly bigger mistake can send you to Colonia anyway ... at which point you have a Shipyard to transfer to because Detention Centres must have one, so it doesn't matter if the station doesn't.
* With AFMUs in the Outfitting and Restock you can completely work around the lack of Repair for anything except power plant, so that's not really adding any challenge other than pointless clicking if it's missing.
* Doing a week-long mining CG with a 4k supercruise back to the station each time is probably more NPC pirates than most explorers want to face without selling their data first. So there's lots of demands for Cartographics, too - and that's not unreasonable, given the balance of risk on exploration data.
But once you've added all of those services, what's actually left for the "CG to get the station operational"?
For standard services, there's:
* Crew Lounge
* Shipyard (on the station rather than the Detention Centre for convenience)
...and that's it.
For enhanced services, there's potentially:
* Tech Broker (way too far from anywhere you could get most of the commodity requirements, but would let you buy things you'd already unlocked from Outfitting - the Guardian sort presumably more popular with explorers)
* Material Trader (somewhat useful for using the remote workshop, or if a Raw trader for juggling FSD boost synthesis materials)
...but again they're pretty marginal.
By the time you've got enough services to be able to comfortably do the CG "as if it was a normal one", you barely need to do it at all. Seems a bit of a waste of the concept if you get there and NPCs have already done all the work. But also a bit of a waste if no-one takes part because it's too much effort either.
