I guess the word "context" has been misused in computer science. An interface is a computer context. In particular, an interface is full of non-negotiating details. A human context is about why (we need it), what (we want), and how (to achieve the goal at high level). Most details at high level is understood as the ways things can go wrong. This understanding provides context when we later dive into the details.

An interface with all its details is an end product. With literate programming, that shouldn't show up as a single piece up-front. It should be developed with layers, each layer with its context (why, what, how), each layer with design and implementation.

Certainly we still want a view of complete interface with all its details in one place. This is the same as the compiler still wants the entire code in its expected structure and order. That's the job of tangle.
