This isn’t meaningfully true. The monkey holding the banana is an example of standard practice OO design. The standard practice for developing a suite of libraries in Go (or indeed in any non-OO language) is to decouple them. They can still work together as a suite of tools, but they can also be used independently. Not sure if this is the best example, but I would routinely use gorilla/mux on its own.
