In software projects, many factors can overshadow the goal of keeping things simple. Technical and non-technical folks often sacrifice simplicity for handling more use cases, improving scalability, easing potential extendability, boosting speed, or enforcing a specific user experience.
While it's essential to consider these factors, I challenge you to treat simplicity as a static, unmoving aspect of your project. Shift other variables to accommodate simplicity. Otherwise, you risk dealing with the same issues most projects face, like instability, higher costs, poor user experience, and increased technical debt.
If you keep things simple at all costs, you will find many of these issues heavily mitigated, and you are more likely to achieve better outcomes.
