Well, "is starttls deprecated" given to search engine gives me

    SMTPS (implicit SSL) has been deprecated/obsolete since
    SMTP+STARTTLS (explicit SSL) was defined in RFC2487.

as the "featured snippet", and there are debates like "SMTPS has
been deprecated since forever (late 90's or thereabouts)"
https://news.ycombinator.com/item?id=10556797

I strongly prefer to keep our documentation out of that mess by not
taking sides.  To me, both are valid options to make the world safer
over cleartext, and we won't have to make recommendations when both
are available.

Thanks.
