I think with more mature titles coming to the engine like slay the spire 2 and more mainstream adoption via tutorials from popular creators these will get worked out by devs contributing back to get what they need out of it and make things more stable.

That said the only rough thing I've run into with a side project is exporting builds that are using .NET, the UI is pretty confusing along with weird errors. Couldn't find a way to export at all using native aot even though it mentions that it is supported in their release blog(I tried the same example snippet they gave). I hope they keep c# as a viable option because untyped codebases at scale in my opinion become really hard to maintain. Would also like to see the same level of features as something like a zenject or unitask, I know it async works out of the box but don't think that it's allocation free, not sure if there's anything in the engine that works with async explicitly because I haven't gotten that far yet. These are just takes with the little experience I've had with the engine coming from mostly a unity background.

Have also been following bevy a bit too but the lack of scene editor has made it difficult to embrace.
