The key is consistency across the organization. Even with a complex (perhaps even over-engineered) standard template, it's nice to be able to open an application/service you've never worked on and have a pretty good idea how to find the key bits. The worst is a huge monolith that has dozens of styles and favorite patterns sprinkled all over from years of opinionated developers leaving their mark. For anything non-trivial, it might take an hour or two just to get your bearings and enter the mindset of the original developer. Then, you have to make the decision of whether your new function is going to follow that (broken) pattern or add yet another new one.
