I always thought the big benefit to recompiling was to allow the use of the latest instructions and system services. If the charts presented by the compiler developers are to be believed, recompiling can have tremendous positive performance impacts, especially when transitioning from one hardware generation to another. If they stop recompiling their applications, and just carry things forward using a copy approach, then their applications might begin to "slow down" (relatively speaking) whenever their systems are upgraded.
