Indeed. The problem is trying to apply the principles of "Clean Code" or more generally of OOP everywhere. There are surely cases where having an interface as an abstraction and multiple implementations makes sense. There are case where it doesn't, and if you take as a dogma "everything shall be the implementation of an interface" you get more complex code and performance penalty for nothing.
There is nothing wrong with having procedural code with a switch case, as there is nothing wrong in having global variables, in having even goto, depends on how you use it.
