Usually, managing a development team is more work than just writing the code oneself. However, managing a development team (even if that team consists of a single LLM and yourself) means that more work can be done in a shorter period of time. It also provides much better structure for ensuring that tests are written, and that documentation is written if that is important. And in my experience, though not everybody's experience I understand, it helps ensure a clean, useful git history.
