Assuming that you are talking about Go, I don't know where you are getting that from.
Go has had excellent tooling from early on. Standard code formatting with gofmt from day 1 was HUGE. godoc, godef, goimports and oracle were also available from early on. And then when LSP came along we got multiple LSP server implementations fairly quickly.
I don't have a link around but I am fairly certain that getting the basic tooling into shape was one of the priorities before the 1.0 release.
