No: https://github.com/Vivraan/godot-lang-support https://github.com/Vivraan/godot-lang-support GDScript is the most tightly integrated into the Godot editor, but there are tonnes of language bindings that work just as well and call into the C++ API just the same. C# is officially supported and they just ported it in Godot 4 to use .NET 6 instead of Mono. I've also used the Typescript/Javascript module from a 3rd party in the past and it surprised me how good the dev experience was. I'd wager that most devs who want to use their preferred language with it are also probably people who don't rely too much on GUI tools and won't miss the few features that gdscript gets from being directly inside the editor.
