Agree, for a lot of code you can be pretty sure it will not change. And you should be able to refactor your code base, if not there are larger issues. In gener

Agree, for a lot of code you can be pretty sure it will not change. And you should be able to refactor your code base, if not there are larger issues. In general I subscribe to the at first make it as simple as possible, when you have two examples of it being too simple it is time to refactor. Of course when creating libraries it is different. In that case to protect users on the API surface and try to make that stable.
