Remarks

Due to limitations of the TypeScript typing system, we need to handle each number of overload individually. It currently supports the max of 15 event overloads which is more than we use anywhere. At more than 15 overloads we start to hit TS2589. If we need to move beyond 15 we should evaluate using a mapped type pattern like {"event":(listenerArgs)=>void}
