"package" in Go has always referred to a folder. Or in other words, a shared namespace for every entity exported by every file in that folder. "module" refers to a package which has a go.mod file in it; that module package + all of its children become versioned via that go.mod file and are distributed as one unit. It operates identically to npm; npm packages are folders, and there's a special package with a package.json which versions that folder and all of its children. Then, that "package.json package" is what is distributed.
