Hmm not sure I understand the question/point. You'd have spent more time trying a new technology than if you read blog posts / listened to podcasts created by people who've used it extensively. You also wouldn't learn much about the legitimate tradeoffs either, because you just won't observe them in pet projects - eg how managed DBs are worth it despite the costs, how multiple standalone Lambdas are a pain to handle when it comes to CI/CD, testing, security updates, etc.
