Let's just say that I fundamentally disagree with that. There is nothing stopping people from making weird contraptions with multiple dynamic parts the same way they make weird contraptions with multiple static parts. What currently limits opportunities for inventiveness is more so a lack of detail by the simulation than too much freedom, right now there is no thinking involved with making a wing in the game, practically any configuration will give the same results. And as such the base game has no real need for the detail dynamic parts allow in this case. When it comes to customizing pods, engines and so on the game is however more susceptible to allowing the users more freedom to make the smaller detail choices dynamic parts allow.
