science isn't when you just decide that things are obvious and leave it at that lol. They probably have data and an experimental methodology and stuff now that future authors can build on to try to answer more complex questions.

On the one hand, the design of Python implies that they think the natural language parts are important. On the other hand, yes we should confirm things that are our intuition says are completely obvious, otherwise when our intuition fails (as it frequently does, see the point about Python) we end up optimizing the wrong thing.
