This is vastly oversimplifying the concept of a “document”. Many times, documents have dynamic content, and therefore must be processed through some kind of controller back-end. Another thing I disagree with: > On-the-fly "building" of documents is, quite literally, fixing something that is not broken. With modern tools like Markdown converters, we can make authoring of documents far easier than hand-coding HTML, so while building documents on-the-fly is less efficient, the efficiency actually shifts to the authoring side of things, and the cost to do conversion is trivial (in fact you could do JIT conversion and cache the result on the server so that subsequent request only delivered the cached cached version).
