When targeting App Engine it isn't developer productivity I am so concerned about but rather user experience as well as cascading failures caused by an initial request failure should the additional time required to fire up Spring DI cause the initial request to go over the allotted total time as per the request quota; Google will throttle back starting up new servers to service requests. Like I said previously, this causes cascading failures.
My mantra for targeting App Engine is Lean & Mean!
