You're not actually supposed to have doExactlyOneSpecificThing methods in AppleScript. Instead, you are supposed to have a small number of verbs that can operate on a large number of objects and their properties. It was REST before there was REST. Unfortunately, this design principle was often misunderstood by those writing scripting interfaces for applications.

It also didn't help that Apple provided very little support for implementing the language's rich query model, which led to many applications only implementing one or two ways to access objects, often with bugs. That was the source of most of the annoyances with AppleScript.
