These things are a form of "premature optimization," which I think anyone can be misguided into, but which younger/less experienced programmers are particularly prone to, because they naturally tend to have uneven skill development, so they'll try to build from strengths before branching out. Premature optimization of typing = complex text editor Premature optimization of debugging = excessive unit tests or formalism Premature optimization of product = coding features without feedback
