asyncio Event Loop does not provide warning about keeping a reference to returned task

Documentation

The high level asyncio documentation warns that one should save the result of asyncio.create_task as the event loop only keeps weak references to tasks.
This same warning is not seen in the low level Event Loop documentation even though the same rules apply. The example code snippets also do not save a reference which would lead readers to believe it is safe to discard the result of the EventLoop.create_task function when it is not.

Relevant function in the high level documentation: https://docs.python.org/3/library/asyncio-task.html#asyncio.create_task

Relevant function in the low level documentation: https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.loop.create_task

比較 asyncio.create_task 的文件與兩個連結文件 URL 中的 asyncio.loop.create_task 區段。更新低階警告及其範例，使其反映高階文件中關於參照生命週期的指引，然後確認兩個區段是否一致。
