I don't see this as a problem. If someone is creating something new they have a reason, something that is motivating them. Explaining these reasons lets others know if the project is something that interests them or not. This is especially important for collaborative projects to attract people whose goals meet your own and who can contribute additional ideas that you wouldn't have thought of without being a distraction because they are trying to pull the project in different direction than you had in mind. It is also important to attract users if that is something you want. Its not justification, it is just communication.
