The thing that always brings this home to me is how much harder it is (for a developer) to rethink a design to remove the need for an option than to not bother and defer the decision to the user. It's sometimes instinctual in these situations to be lazy, but a small amount of reflection (try having a conversation with an imaginary Steve Jobs) makes it obvious that the time and energy cost for you will be easily justified by the time saving for a non trivial amount of end users.
