If you embed a section, like for a quote,
then no header should be inserted.
And when using CSS you can decide to have the title removal in a snippet (or class) of its own. That would allow for the addition of that class either through cssClass or some of the class adder plugins. This would allow for removal of titles on at least a per file basis, or possible (using the plugins) related to that particular embed.
So options do exist…
