Good morning ^^ Thank you for your reply.
There this esoteric programming language, which is formatted like a letter to Princess Celestia. It's called FiM++ and was made back in 2012. But it's nothing for big projects.
About engine development - a couple people I talk with here and there may migrate from Unity to Godot. Since Godot is Open Source some Ponybro may contribute to the source code, because a feature is missing. By just using it and voicing wishes for the future also helps.
Unity says they want to democratize the developer market and frankly, they really do. Many devs are now looking for other engines and will contribute, iterate and improve the landscape for all of us. In the middle of this chaos it is good to see that we will help each other in direct and indirect ways.
