Even something like Burst is, IMO, not really necessary in modern C#/.NET. It does well in benchmarks but they are almost always comparing Burst vs. normal C# in Unity. Problem is C# in Unity is stuck so far in the past that it makes Burst look amazing when it's usually not that much quicker. So if you are using modern .NET you're not restricted to a subset of C# and get good performance. And if you need even better performance there are plenty of new language features to get you there.
