I agree, these rules make the code extremely verbose and over abstracted and scattered. The resulting code base will be several times the size of a straight forward solution, and this has a very big negative impact on maintainability. Even if you use many files and only put a tiny amount of logic in each of them, you still need to have an understanding of the overall system and how things work together, and scattering things in more places, each with multiple wrappings, just makes that even harder.
