I don't have a garage door opener myself, but from what I've gleaned from US YouTubers is that they like to know the _state_ of the door, open/closed which is handy if you use home automation.
I imagine if you're driving into the garage from outside you have a physical button in the car with you to open it, and if you don't run home automation, the "automation" part is likely not very useful.
