I have to say that I am surprised how lightly everyone is taking the
ISS safe haven concept for Shuttle. What if a Shuttle is stranded at
ISS, and something goes wrong with the next Progress that is required
to keep the 10 person crew going? Is the ISS safe haven truly 2 fault
tolerant?

so, what is the reason?

Seems perfectly simple and well-defined to me. No on-orbit repair
capability because it's too expensive, no ready rescue flight because
it's too expensive, so all shuttle flight go to ISS as a safe haven.

What's so hard to understand about that?
