It's hard to tell which camp is more angry: the C# developers stating Microsoft is ditching its own ecosystem or the Rust developers unwilling to accept anything in this category not being written in Rust.

From my understanding, all three options (Go, C#, and Rust) represent a significant speedup. The only legitimate concern I see is the one around WASM support, which is quite valid.

But at the end of the day, it seems like the team is making a decision that maximizes speed and deliverability, with the offset being that some cracks are now present (e.g. WASM). I can respect them for that choice.
