Which is exactly why static analysis tools that force you to do something need to be shot. Static analysis tools that inform you about a possible duplicate are totally fine. Give me an option to disable that particular instance.

Co-incidentally, micro-services do away with such problems in many cases due to the fact that code is "separate" and thus analyzers and sticklers don't find the "duplicates" and you can write beautifully simple code. Unfortunately it has the opposite problem then of leading to things like this Netflix architecture https://res.infoq.com/presentations/netflix-chaos-microservi... but for something simple like a personal blog (yes I exaggerate - slightly)

In the end I think the only solution is to have the right people and stay small enough to keep the right culture. That probably goes against all your metrics and growth goals of the company of course.
