I think this kind of understanding is really important too, if speaking to native speakers of a language. You're level may be basic and not super fluent, but if you can make yourself understood you can have a conversation. But if your listening comprehension is not good enough and the person is not slowing down (or if it's multiple native speakers speaking at a natural cadence) then you're lost.
