Delusional project planning kills products and companies. How many years before Starship rockets achieve rapid reuse after being caught by launch tower chopsticks and are reflown quickly enough to supply a yet to be designed and launched orbiting fuel station before the fuel and oxidizer boil off so that Starship can go beyond Earth orbit?
The critical path will bite you in the ass especially if your idea of project management comes from software projects. If you pile on enough dependencies, especially on untried concepts, you might not know which possible critical path will bite the hardest.
Boil-off can be prevented by loosely wrapping in 50~100 layers of aluminized mylar ("space blanket"), adding some solar panels and heat rejection panels, and a 2 or 3 stage refrigerator to keep the contents cold enough to not trigger the boil-off safety overpressure valve.
If you're clever with the orientation or possibly with a movable sun shade, you might even get by with just using space as a heat dump, by insulating against the earth and the sun and exposing to empty space to radiate the leakage heat away without a refrigerator.
I think they have enough experience with orbital electromechanical design to make this not a problem with much suffering.
