Not exactly. The dev has the power to control the level of complexity of his game, keeping things within a scope that one person alone can accomplish.I understand developing a game by yourself is hard, and I get it that the larger the game becomes, more and more time it takes to develop. But at this point I'd be okay with another "hey guys, I'm dead but I'm fine" post.
The thing is that they're very often driven by the audience/supporters desire for more things, more complexity, more fetishes and systems, and this all increases the scope of the game drastically.
It's a basic skill that a solo dev must have to simply know how to say their audience: "No, I'm not going to add this complex system, I'm not going to add 30 more fetishes because I can't write it all, I need to think about keeping things handleable so I can one day finish this game."
