The whole premise that the "communication of this rule has been weak" is rather weak. It has been hammered in throughout the development process of modules, and is part of the official documentation. If the author has missed the numerous blog posts throughout the development, and hasn't read the official documentation, well, I'm not sure we can fault someone else for that. Luckily, it appears that the community has picked up the memo somewhere, as there are quite a few v2+ modules around.
