Ah, that makes sense, yes.  (I might have added that Org entry to my
local mime.types and forgotten about it.)

Thanks, that looks good.

I think that should be fixed by using the appropriate export option,
like this:

  (cl-defmethod elpaa--section-to-html ((section (head text/x-org)))
    (elpaa--export-org (cdr section) 'html
                       :body-only t
                       :ext-plist (append '(:html-toplevel-hlevel 3)
                                          elpaa--org-export-options)))
