The apparent discrepancy between “the simplest thing possible” and “the best solution” only exists if we forget that a product exists in time. If the goal is not just an app that works today but something that won’t break tomorrow, that changes what the simplest thing is. If what seems like the simplest thing makes it difficult to maintain, have many poorly vetted dependencies, etc., then that is not really the simplest thing anymore.

When this is accounted for, “the simplest thing” approaches “the best solution”.
