It didn't work either time. In the second case it just did some other stuff before noticing. Before modules, it made sense to "go install" a non-main package: that would build the package and set it up to be imported by other packages. With modules, though, it doesn't make any sense. The go.mod file specifies exactly what version of a non-main package to use. And the compiled form of packages is stored in the package cache. Installing a non-main package isn't going to affect how anything else is built. For a while it was available essentially a no-op. Now it gets an error.
