I don't know why you got downvoted dead. I think it's an interesting point. I don't know if you're right, but it was an interesting premise to think about. Certainly people have for a long time licensed engines made available as a side effect of the creation of a certain type of game to build further on what's been accomished, or to cash in by making derivative games. For example all the shooters made with the Quake engines, which no one would call general purpose. There's a few examples of reused RPG engines (e.g. Infinity Engine) and RTS engines, too. There's also plenty of toolkits dedicated to adventure games and visual novels. Arguing growth is possible is not outrageous.
