I've just installed `golang-github-burntsushi-toml` that should be the well known Go TOML library; asking `rpm -q -l` shows mainly `*.go` files, thus I assume they are mainly used as build dependencies?
Hmm… That makes sense. Though if you are building from source, the only gain you have over regular go tooling is downloading from your favorite mirror rather than github&co. I hope it doesn’t install these source-packages for prebuilt binaries…
I believe they don't allow internet access during the build (so everything needs to be vendored, or things stuck into GOPATH); those packages are probably for the second option.
My impression is that OpenSUSE go packaging is a bit behind though. But I'm not an active packager so this may have been fixed.
