Agreed on that point. The Office team made a wonderful job at this, by also putting actions in the title bar (e.g. by default: save, undo, redo), but making it configurable. However, MS has orders of magnitude more dollars to develop/support/bugfix the added complexity, and given the hate of GNOME committers regarding anything configurable, I doubt that will ever happen in GNOME.
I'm not bothered by it because, like others here, I use keyboard shortcuts for 99% of my actions and never need to reach for buttons or the sandwich menu, but I understand why I'd be bothered too if it wasn't the case.
