What I'm not sure about with wilderness refueling is whether it includes gas giants with water oceans (or not) as an acceptable fuel source.
Ideally, I would want to have separate options for:
- Purchased Refined Fuel (basically type A/B starports only): Y/N?
- Purchased Unrefined Fuel (basically type C/D starports only): Y/N?
- Gas Giant Skimming (requires partial streamlining): Y/N?
- Water Ocean Refueling (requires atmospheric streamlining): Y/N?
