"Good Programmers write Portable Code" seems a bit of a hasty generalization. Good programmers write portable code if portability is a goal of the project. Portability, as you define it, comes at a direct cost of maintainability, and potentially the ability to add new function in a reasonable manner. A large portion of "good programming" is about making tradeoffs, and making the correct decision. Prioritizing portability is a decision that can be made, but that the decision is made one way or the other within the scope of one project does not mean that the decision-maker is a "good" or "bad" programmer.
