I on the other hand like the fact that Go keeps things simple and primitive.
Don't need those functional constructs at all, allthough I'm using them quite often in Typescript.
But for Go - please no. Go is like C. Adding things just makes it worse.
My favorite language is by far Java with Go a close second. I dislike the others. The only thing I wish Go had is more functional support, but only in the style of Java's fluent API. I strongly dislike PHP, JS, and Python functional style and would almost prefer they not exist.
