Python 3.14 makes that choice directly available through the <code>eager_start</code> keyword on <code>asyncio.create_task()</code> and through task-group task creation.</p> <p>That can remove scheduling overhead for coroutines that often complete without blocking. It can also change program ordering in ways that matter much more than the performance gain.</p>
