Ha ha! If that was an actual argument then I would argue against that.
To be real, if someone has to constantly fight with the editor that will demotivate the person in which may turn them away from the at least editor.. or worse yet, the entire engine. Especially when this engine is marketed towards beginner level indies. With tiny features (or shortcuts) like these, it will help make the design process less stressful and quicker which may spark more creative designs. I don't want to have to fight with the editor constantly just to design something, that is what I feel like I'm doing at times, especially when it comes down to the Flowgraph editor. Luckily, I do have lots of patience... which is a MUST in game development.
