…eate_task The low-level Event Loop documentation for create_task() did not repeat the warning from the high-level asyncio.create_task() docs that the event loop only keeps weak references to tasks, so a task that is not referenced elsewhere may be garbage collected before it completes. Mirror the note (including the fire-and-forget collection pattern) in the loop.create_task() documentation.

The high-level :func:
asyncio.create_taskdocumentation warns that the event loop only keeps weak references to tasks and that unreferenced tasks may be garbage collected before they finish, but the low-level :meth:asyncio.loop.create_taskdocumentation did not repeat this warning.This mirrors the warning (including the "fire-and-forget" collection pattern and the :class:
asyncio.TaskGroupalternative) in the :meth:asyncio.loop.create_taskdocumentation, usingloop.create_taskin the example.Linked PRs
