Civil Aviation

Something I've been a bit confused on about this: my understanding was that generally, crew capsules that a crew went up in were kept docked so as to serve as an escape mechanism if for whatever reason the station has to be evacuated. I also had read that while they couldn't be sure that returning in starliner was safe, they at least previously thought it probably safe, just not enough to be sure of, and in an emergency scenario would still have been more likely than not okay to use. With the starliner now having been returned to earth then, is there a plan for it's crew in the event of an evacuation? Is there sufficient room aboard other crew vehicles to return them in such a case, for example?
