I think you miss my point a bit. It's not about what can be done with those ecosystems in 2026 - you mentioned what was done in the 2000's, and I'm suggesting one reason that wasn't perceived as "cool" is because of the whole VM / overhead requirement. Maybe technologies for that existed then, but they certainly weren't being used much - every experience I remember with Java back then was "download this jar, now go and get yourself a JVM to run it".

And I do still think there is an advantage for this kind of tooling to choose languages that are designed to compile to a native binary. At best Java and C# are equivalent to Go and Rust here, maybe they are less "cool" but I don't see any reason why this rewrite would be better if it were to Java than Rust.
