It's not so much the problem being simple, but more about it being a problem you have already solved. If you give me a blitter API and ask me to write a composited then yes, I can churn out the required quantity of code with ease each day. I know the problems, I know at least one solution, so I won't ever have to head up dead end alleys, stop and research options on the Internet, discover that I've chosen a really inefficient algorithm that requires a near complete rewrite to avoid, and so on. Ask me to patch an existing code base that I'm unfamiliar with to add a new option on a settings screen, and those 5 lines might take me two or more weeks to write, even though the task is simple.
