That assumes that your information is presented in such a way that the
main headline comes first.

That is the most common way to do things, and there are good reasons for a
"pyramid" style where you start with a headline, but there are real use
cases for beginning with something that isn't the most important element.

On the other hand, if you are using e.g. h4 but presenting it visually as
something more important that what is represented in h3, I think you're
pretty clearly doing the wrong thing - not just for accessibility but HTML
in general.
