Comment (by rmccue):

 I disagree with close; core generates URLs ''by default'', but there's no
 reason a plugin can't change this. It can actually be intentional to
 change this, as otherwise when migrating domains, you might be left with
 GUIDs containing the old domain.

 I've seen sites change these to URNs instead (which would fail validation
 on `esc_url` right now I think, since presumably we don't allow the `urn`
 protocol). I think we should continue to support this.
