Yep. And for some articles the byline could be seen to be introductory.

No, the spec gives examples of what kind of things a footer "typically"
contains, to aid understanding the purpose of the element. It is clearly
not a definitive list (it says "such as" and "the like"), is and does
not say you "have to" do anything.
