Could Courageous have validated carrier anti-submarine warfare?

Would Courageous sinking her attacker have preserved the concept of carriers hunting submarines?

It would have helped, but the concept already had evidence from exercises and aircraft successes dating to the First World War.

A successful attack by Courageous's aircraft would have strengthened the case for carrier-based submarine hunting. It was not essential proof, however, because exercises and wartime experience had already shown that aircraft could find and attack submarines. British aviation had relevant successes dating back to the First World War, so the operational idea did not rest on one hypothetical encounter. One dramatic demonstration would have reinforced an existing body of evidence.
