I can't help but think this is delusional. Microsoft has put massive effort and funding into C# and I just don't see how Godot, being much more niche, can reach that level of investment.
If they targeted the .NET VM they'd be able to make use of a lot of that investment. But they don't really need to. There's a lot of low-hanging-fruit for performance, and narrowing the gap is more important than outright parity.
