alt Hacker NewsC# doesn't (and can't) use WASM GC.
The comparison is unfair for other reasons (the C# runtime was optimized for WASM size and the Rust not, it's possible to be much smaller in Rust), but it's still cool.

Is the support gap mostly related to weak references and finalizers? Or is something else missing?
(Obviously those are already pretty significant gaps.)

Any cross-language benchmarks are always unfair for those kinds of reasons, because ultimately everything is eventually possible against any given hardware.
What matters more for comparing what you get out of languages is the output of idiomatic code written against typical frameworks.
Indeed, it's still cool to see, even if it's optimised to beyond recognition, as seeing the occasional C# win is nice to keep the "re-write in rust" wolves from the door, who seem to ever lurk, especially in a world where re-writes appear easier.
