The continuation-based libraries are the simplest, easiest, quickest way to get a program off the ground. They make interactive Web programming just as easy as writing “scanf” or its equivalent, _and_ are safe in the face of various browser interactions. Therefore, they're a good default for prototyping. However, I agree that they also have issues, and the documentation should not over-emphasize them, but rather indicate what they are suitable for and what not and make clearer to readers a transition path out of there.
