I wouldn't call it a grand plan, but it is one of Google's five officially supported server languages and as a result there's a lot of work being done to build tools and libraries for it. Code generation and relying on language-agnostic building and packaging systems (bazel) are both pretty common Google-isms, which show how the company's development culture influenced the priorities and direction of the language.

What are the other 4? Python, C++, Java, and what other language?

Javascript

Not a server language (no NodeJS at google). The other is C.

AFAIK (although I could be wrong about this) the typical 'five' languages used at Google are not specifically for servers. I have heard they are Javascript, Java, Python, Go, and C++
