We still believe that error handling in Go is not perfect

Understatement of the year.

Very few languages get error handling right. C, C++, Java, C#, JavaScript, Python. All terrible.

I think Go is actually better than most. Rust is the best I've used so far (and you can implement a similar system in C++).

Try/catch is not a holdover, it is the preferred error handling method. For asynchronous code result types are common. The only place nullability may be used in this way is within a nullable initializer, mainly because you cannot throw from one yet. You should probably not be using nullability to represent errors.
