Do not put code in your program that might be used. Do not leave hooks on which you can hang extensions. The things you might want to do are infinite; that means that each one has 0 probability of realization. If you need an extension later, you can code it later – and probably do a better job than if you did it now. And if someone else adds the extension, will they notice the hooks you left? Will you document that aspect of your program?
