This is not a prototype, this is a surgeon performing production-level work. It's the same as if you had to whip out a basic service (as trivial as it core domain logic could be) but with all the details it need: deployment pipeline, monitoring, logging, a future-proof architecture (or do you want to be living with subpar heart surgery because the prototype was faster to deliver?).
The analogy breaks down very quickly, I just wanted to demonstrate how absurd your statement is.
It is entirely possible that looking at how to perform the procedure prevents fringe failures of surgery. Imagine your surgeon does his job extremely well but it turns out he performed the wrong surgery on the wrong patient because he trusted his memory too much.
