For example https://deno.land/x/ is effectively nothing but a URL redirect server, where it rewrites URLs to include a git commit-ish reference in the redirected URL. So https://deno.land/x/oak@v4.0.0/mod.ts becomes https://raw.githubusercontent.com/oakserver/oak/v4.0.0/mod.t..., which GitHub serves up a nice versioned module.

Thus http://deno.land/x/ is the de facto central registry. I'm yet to see how it makes a difference whether the logic of resolving a package name to a concrete version of the package is baked into command line tooling or a web service.
