Simplistic protocols and models and language features can end up becoming complexity multipliers because the complexity is duplicated by each and every user of the model or protocol. They are also effort multipliers. Fortunately, one can sometimes solve this problem by wrapping or refactoring the protocol or model or language feature within a library to utilize it, thus capturing the Essential Complexity into the library and thus creating the feature/language/model that should have existed in the first place.
