I'm not an expert in this field but I feel like the key is to make Dragon as a platform cheap, and once that happens more rides can be carried (to ISS) hence making the system battle-tested. Being cheap and reliable are the two major reasons NASA rode with Soyouz in the past few decades and, for better or for worse, still riding with them even after the Ukraine war started.
