Absolutely. C# in Unity always seemed to me like a square peg in a round hole.

From my perspective (teaching game programming classes), it's incredibly clunky for beginners when compared to others. Unity needed a tightly integrated, noob-proof scripting language. Despite C# being the primary language, it's integration and setup with the rest of Unity seems surprisingly lacking, and, like you're referencing, you don't even get convenient use of the broader C# / Mono / .net ecosystem, which makes skills more portable. Even the "bad old days" of Flash/ActionScript were much easier for students, and results in more portable coding skills (e.g. at least transitioning to Web / JavaScript from Flash / ActionScript is easier)

It's much easier to teach same lessons / concepts using Godot, though sadly Unity is much better known. Hopefully the present pricing chaos might shift the needle a bit on this!
