I'm seriously not trolling, but why does every Go project need to say "written in Go"? You don't see things like "Linux, a kernel written in C", "Homebrew, a macOS package manager written in Ruby", "Nginx, a web server written in C", "Git, a VCS written in C, shell, ..." etc.

Hi,

It's just to say that it is a library made for people that work with Go. This is not to especially mention that it is written using Go language ;)

Doh! Sorry, my bad. There are too many posts like this and for a library, the phrasing is a little odd since I would expect a Go library to be primarily written in Go. I suppose a Go library could be a wrapper around a C or other type of library, but that would not be something worth emphasizing, IMHO.
