That is wrong IMO.  Title is mandatory in at least HTML{4,5}.

    https://www.w3schools.com/tags/tag_title.asp

AFAIR Org already allows invalid HTML document to be produced when the
TITLE is empty, as it’s translated into an empty quote.

The right approach IMO is not printing the h1-title block, as in the
attached patch.

(In general generating the title block should be moved to something like
‘org-html-preamble-format’, though it probably shouldn’t depend on the
language of the document...)
