I think having things in production gives you valuable experience that you can use to make better software next time. Things like reading all rows into memory before processing them is convenient and works fine in dev, but can fail spectacularly in production. There are a lot of little things like this that can bite you. And you often won't even be aware of them until they are tried "for real".
