Ah, gotchya. Yeah it was quite jarring to see that leaving the open_dataset context manager didn't produce any noticeable change in the data accessibility.

In my passing opinion, it seems like it would be best to protect people, especially those who don't understand what context managers do, from themselves and have a closed dataset raise upon being queried. This is how all "closed" objects behave in my experience.

I'll leave this issue open in case there is any useful discussion to host here. But feel free to close it if that is more appropriate.
