It is more a matter of chemistry and thermodynamics than mechanics.
Most of the reason people go richer is to compensate for knock and then try to edge out more power. The power you make in that manner is fragile at best, and catastrophic at worst. Cars tuned this way are temperamental and unpredictable.
In this case conservative tuning isn't running richer, it's running MBT and the appropriate ignition timing to suit.
