I've been following this proposal around for the past few months, it's really interesting. Godot could be the de-facto library for complex 3D rendering in any app since it's really feature-rich and not that huge (I think the runtime is like ~60 megabytes? It could likely be smaller with further optimization and stripping features you don't need).
Also I don't remember who said this but if this goes through it could allow C# web builds by loading Godot is a library.
Kind of a shame this came as 4.3 is in feature freeze, it would've been nice for it to be included in the next update.
The only thing I'd like is fact-checking itself, which is impossible considering how they work (it basically guesses everything). LLMs are close to being useful but I find most of the time they're not usable because it keeps spouting wrong info.
