When evaluating technical solutions, ensure that your preferred solution doesn’t suffer the same (or super similar) flaws you would use to reject other solutions.

People are fascinating. I’ve read a slide deck where « Simplicity--the art of maximizing the amount
of work not done--is essential. » from the Agile Manifesto was the justification of doing a massive system fully configurable to reduce the amount of work when changing something was needed 🤷♂️

The quote "All models are wrong but some are useful" should not be read as an excuse to stick with your model. It's a call to actively search for more useful models.

This. Lack of refactoring is an agility killer. If you don’t know how to refactor you are afraid to touch a your code and feels the need to be right the first time or to include “maybe one day” extension points
If you can't change design cheaply because refactoring skills are lacking, you're less likely to end up with a suitable design for a given problem that emerges from insights you get as a byproduct of refactoring.

A cruel irony of coding agents is that everyone who blew off automated testing for the past 20 years is now telling the AI to do TDD all the time.
But because LLMs were trained on decades of their shitty tests, the agents are also terrible at testing.

Another simple source of simplification is not having a generated ID and a natural id to use for referential data that no user can change. If you are lucky enough to have a natural ID use that. The same one in all environments. Stop mapping!
