Why do I keep seeing people that use #Emacs #OrgMode with an external static website generator, usually Hugo, to make a website? Is there something wrong with the org-publish subsystem that comes with org-mode? It seems to work well to me.

Or maybe there's nothing wrong per se with org-publish, but Hugo is somehow better? I can't really imagine Hugo is more extensible than org-publish, but maybe it's better in some other way?
