Yes, It is true. In my opinion, if you have lots of time. Then start a project from starch.

The production code size is the same or increased slightly in both cases. In the end, performance and stability matter for the app.

Suppose you use a third-party library in your app. You have to write less code, and code writing speed is better, less testing and speed up your development workflow, which is a matter for companies or developers.

Thanks

Great questions
