The actual specification of article and section elements in HTML is pretty much what you said.

My issue with them is not with their roles, but with their names. And, from the article and from OP, it seems I'm not the only one. I think "region" as it is used by WAI-ARIA would be a better name. Also something like "contentinfo" instead of "footer". And "complementary" instead of "aside"...

> E.g., if we were to scrape any content from an existing site in order to reintegrate it for a relaunch or a similar purpose.

The spec call this "outline".

Related to divs. I find ironic that making pages with tables were frowned upon 20 years ago, yet it is hot again now, but we are calling them "grids".

They say, the lack of usage of hgroups is due the lack of support by screen readers. Another common use case is <h1>Chapter 1</h1><h2>Foobar</h2>.

Regarding the table irony, see also the common use of table, table-row, and table-cell display styles for anything but actual tables. ("If I'm using divs, it's fine!") :-)

(Tables should even be more accessible, since there is <th>, both in <thead> and with `scope="row"` for table rows.)

Something, I've been guilty of (sometimes) for emulating hgroup: <h1>Heading<br /><small>Subhead</small></h1>.
