it is not the capsule that is the problem, its the service module that has the thruster issue and the helium leaks.
But how could anyone be expected to trust the capsule if its service module is nothing but a boat anchor?
And I just read today that the Boeing craft must have a crew board in order to undock. So they can’t just undock it and release it in an absolute emergency, it’s attached until they get a crew on board. It’s possible a software update may allow for automatic undocking. But boy with their luck I’d make sure the airlocks were closed first
