That's kind of part of the problem - with C++, or Java, or C#, you can write in 15 different styles, syntactically valid but quite possibly unreadable to another programmer who is experienced in the language. That's because there isn't one idiomatic standard for the code, there's 15++, and the language has the complexity that enabled that mess.
If you want to work in a kitchen sink language (and I often do haha), just use one of the many available.
But perhaps you're missing the value of simplicity? It is after all the main strength of Go, and a rare commodity in software engineering these days.
Overall I think it's a shame to have less choice, and we lose something by making all languages too similar (in both features, and at the meta level in complexity).
Not really, for me Go is a bit like JavaScript.
I have to deal with Go thanks to Docker and K8s, doesn't mean I would use it when given the option.
