+Support for golangci-lint-langserver is
+[built-in](https://github.com/emacs-lsp/lsp-mode/blob/master/clients/lsp-golangci-lint.el)
+to lsp-mode since late 2023. When the `golangci-lint-langserver` executable is
+found, it is automatically started for Go buffers as an add-on server along with
+the `gopls` language server.
