I'd argue domain knowledge becomes less and less important as the size of the organization grows. Eventually, it gets to the point where what you are working on is just a tiny piece of the overall work, it just doesn't matter. Also, at that larger size, your input doesn't matter very much either, that's what the BA team is there for.

The best organizations will work to leverage the productivity of individual devs over just throwing bodies at the problem, but that doesn't happen everywhere.
