In fact, ExitStack can itself be used as a no-op context manager, if you want.
I didn't think about this. So yeah, my proposal is useless. Nevermind.
Not at all. It's a good use-case, and it helped introduce/remind us about ExitStack (which I suspect is a hidden gem).

Python 3.6 also has a context manager ABC so you could also use that in 2 lines for a dummy context manager.
