When I use a Handler, I would like to add specific logic to the handler and next to that I mostly what the default insert, update, or delete to be executed.
Currently I have to add and maintain the default logic myself, which takes a lot of time and increases the risk of errors.
As a user, I would like to indicate that I want to use the Handler and have the option to indicate whether or not I want to use the default insert, update, or delete. And if so, have the SF generate them for me. This way, I only need to develop the specific logic.
