So everything in unix has some text file controlling every aspect of configuration. If something goes wrong, you reconfigure it. Configuration and choices are often a cowards way out. Push the engineers problem on to the user or support people, and dodge their responsibility. But it also means that some don't have the levels of control that they think they need.
All systems have good and bad points.
Imagine you could reconfigure a car so that the pedals could be reversed. They should also know how to switch them back. It doesn't matter that drivers will making mistakes since their reflexes can be trained only one way. Many want their BAD configurability anyway. But since it has so many costs, and so few returns, less choice is often better.
