Yes, I think so. I hope we can soon have some concrete examples of intent, because for a long time the discussion has been very abstract.

As networks get more and more complex, and especially when virtual networks or slices are created dynamically and automatically, the administrators will *not* have complete knowledge of the underlying network. In fact, the intent itself may be the reason for this: the network is configured as a result of the intent, and the human administrators will then be unaware of the details. (They are presumably aware of the physical structure of the network, and the devices installed, but that is only part of the story.)
