Ryujinx has replaced Stack Overflow as the canonical "C#/.NET" showpiece. And it is fantastic for it.
The engine is C++, the C# integration is bad, the new ECS translates C# to C++ (or some cpp like IR) before it runs, and the whole thing is closed source and openly hostile to open source (eg. package managers) that might damage their revenue from the asset store.
Don’t get me wrong; modern C# projects are pretty cool, but this is way cooler than Unity.
This makes me suspicious of your take seeing as IL2CPP has been part of Unity for years and years and not the ECS stack.
They also have a package manager now as well as custom/3rd party repo settings.
But on the whole, yes. Unity is not a shining example of C#. Although its an example of how far you can hack with it.
Burst and IL2CPP are different things. Burst is also a different “can’t believe it’s not c#” custom layer they invented, own and now have to maintain a separate fork of.
(Apparently just maintaining IL2CPP wasn’t keeping them busy enough)
Ie. no. It’s not done. No one knows when it’ll be done.

If you’re really keen, just read that whole thread and you’ll get a really good understanding of how great things are, how happy with the c# support everyone is.
Tldr: netstandard 2.0 != .net 7 and nuget support.
