Then why not just say "single binary, no dependencies," rather than bury it under an additional layer of abstraction? A humblebrag is still bragging...
Because saying it was built with go says "single binary, no dependencies" and more. It also says that it was built in go for any developers who want to contribute.
I've never seen a language so obnoxiously namedropped as Go, it's really annoying. We have such a hard-on for our tools, and it really only results in countless, needless lines drawn in the sand.
