After some overly-aggressive cleaning of my GOPATH, vim “hung” with the message
“vim-go: initializing gopls” the next time I edited a .go file.
I discovered that running :GoInstallBinaries in vim would “fix” the
problem and re-install the missing packages.

Unless I’m missing something, go seems a bit lacking to me in its package management tooling. I don’t see a good way to “clean up” unused packages without removing dependencies from another package.
