Honestly I think the biggest benefit of reproducibility is just debuggability. We both check out the same git repo and build it, we can later hash the binary and compare the hashes to know we're running the exact same code. On security, if you really care about compromised build servers you might as well just build from source yourself. I think reproducibility might matter most in systems where side loading is hard/impossible like app stores, but I'm not familiar with the current state of the art in terms of iOS reproducable builds and checking them.
