I think you're _assuming_ "more control" is a substantial benefit for them.

Right, but if you don't see a strong use case for that control it isn't a benefit. The examples you gave were of changing the UI in a way I am not interested and a way of triggering emails and slack messages when I save a file which would be actively harmful.
Giving me the ability to do something I do not want to do is not beneficial. It's like telling me a car is better because it's so modifiable I can install a Margaritaville. That would be a bad change to me so it's not selling me on the benefit of this car.
