I'm sure it is, no doubt its easier to pick an existing language than build a whole new one.

For me however, the benefits of an existing language outweigh the costs. If Godot were to use Python for example, you'd gain the full benefit of pip alongside it. If you use C# with Godot, I know you can use Nuget. I'd also personally rather a more performant language than one thats easier to write, but thats personal preference.
