pkg.go.dev supports fossil-scm (and I believe any "go gettable" source repo). So, the idea that it "hard-codes a list of centralized git ..." needs a citation.

Whereas AFAIK godoc.org only supported git. IMHO support for a variety of SCMs makes pkg.go.dev a huge improvement.

Support for "go get" and pkg.go.dev via fossil-scm does require some golang-specific meta tags, as TFA exclaims. But why is that a big deal, it's a golang repository after all?
