I believe types are a great way to encourage good practices with relatively little investment. They provide type-safety, act as living documentation, and add an extra layer of protection in production.

However, in a large codebase, consistency can become a challenge. Different developers often approach the same problem in different ways, leading to a mix of type patterns and styles, especially when there’s no clear standard or when the problem itself is complex.

With the rise of LLM-generated code, this issue becomes even more pronounced — code quality and craftsmanship can easily degrade if not guided by proper conventions.
