Those of us experienced in DevOps have been trying to set standards for repo/project structure, deployments, etc. for quite a while, but it seems like every developer has their own idea of what they did the first time they read a blog post about "how to build X app" and then will use a different structure after they consume their next Medium article. Or, even better, they're been "doing it this way for 10 years", or "I heard Facebook/Amazon, etc. does X".
