A placeholder that does nothing yet has also been added for session writers.\n\n**Why**\n\nThis may let a program send a message to a task that is already running, the same way it can already stop one.\n\n- Area: SDK\n- Names: `send_task_message`\n- Tier: Use it now\n- Useful: 4\/5\n- Signal: 3\/5"}
