Graf Zeppelin's aircraft choices and the solo-carrier problem

Were Graf Zeppelin's Bf 109 and Ju 87 choices sensible, and was Germany unusual in considering solo carrier operations?

Using proven aircraft was sensible, and other navies also experimented with exposed carrier employment, but carriers still required escorts and a balanced force.

Adapting proven Bf 109 and Ju 87 designs was a sensible starting point for Germany. Germany was not alone in imagining exposed carrier employment, but Courageous and Glorious at least sailed with destroyers. The exchange separates a defensible aircraft decision from the much riskier idea that a fleet carrier should operate without a balanced escorting force. Proven aircraft could reduce aviation-development risk, but they could not compensate for unsound employment doctrine.
