You just weren’t doing anything that depended on your model of cosmology. I don’t think that says much about how tolerant of bad models the modern world is. The engineers making GPS required good models of physics, but their efforts probably would not have been thwarted by even the most inaccurate models of human medicine. And likewise it’s probably fine if your doctor doesn’t know about relativity.
