Good union types in Go would probably need types without a zero value

Thanks for your input! All the design proposal RFCs have shown they cause an issue with the Go Compatibility Promise whereby adding any enum value can cause a semver-MAJOR breaking change. This causes a greater rate of ecosystem churn which, in every design proposal so far, has been deemed a net negative outweighing the modelling benefits.

Yep, I'm aware. The question you asked was about the Go language designers ignoring the fundamentals, which is the root cause of this situation today where fundamentals can't be bolted on to the language later
