Why would one want to couple these two? Doesn't that couple, say, your API interface with your database schema? Whereas in reality these are separate concepts, even if, yes, sometimes you return a 'user' from an API that looks the same as the 'user' in the database? Honest question, I only just recently got into FastAPI and I was a bit confused at first that yes, it seemed like a lot of duplication, but after a little bit of experience, they are different things that aren't always the same. So what am I missing?
