It shouldn't be slowing good developers down, it should just be changing the order they were already doing things. One of the most fundamental ideas I took away

It shouldn't be slowing good developers down, it should just be changing the order they were already doing things. One of the most fundamental ideas I took away from my Software Engineering course in college was that catching errors early in the development process is more efficient than catching them later. It is a lot faster to grind out ideas in the planning phase than to churn during code review, because the development and code review processes are a lot slower than just replying to comments. More importantly, when experienced developers formalize their reasoning for a proposal, less experienced developers can learn from it. That same knowledge becomes archived in a format that is easy to discover and consume in the future.
