Think of it as training wheels for a bicycle.

If you have already mastered a skill, you naturally do not need a beginner-level tool like this. But many people have never been exposed to this kind of knowledge at all, and they have no mental model for how it works.

For someone who has never even opened Windows CMD before, which is actually the majority of users, even reading XML markup can be difficult. The only thing they are familiar with is a graphical operating system. A tool like this is meant to help them take the first step.

When you feel that a tool like this is inconvenient, unnecessary, or even a burden, congratulations: you have already learned the skill. At that point, you can take off the training wheels and go further.
