I don’t even have all safehouses…
They all got lost from one day to another (multiple times!). Just the mission related ones (bunkers i. e.) are still there.
It’s not a “need to know”. It would just be a nice additional info to safe time. Of course you could just fast travel to the home base where you propably have all stations.
But there are players who don’t have the homebase yet. Or players don’t want to fast travel. Or they are overloaded and don’t want to drop something, because they farmed a ressource they need and then need a recycling station.
There are also places with a vehicle station or a apparel crafting station but nothing more (no safehouse), or even a safehouse without a plundra (not 100% sure anymore).
