I don't know anything about this, but there are certain times when I have liked to use \paragraph{   } in generating a document.  The first part of the paragraph is emboldened, but it's still a paragraph.  I stumbled over this idea when I first encountered Org-Mode, and never was satisfied with the answer that it's not possible to wrap a headline.  On the other hand, I do understand that concept and a little bit about why it isn't ordinarily a great idea.  We are not talking about exporting though, and it's entirely possible that this is possible to do when exporting. 

FWIW.

Semantically, this makes no sense?  How would org know that the line
that follows a headline is part of the headline or not part of the
headline?

I appreciate that your example from Emacs news in that it mis-uses
(abuses) outline headlines...

The use of corrupt manipulations and blatant rhetorical ploys ...--- outright lying, flagwaving, personal attacks, setting up phony alternatives, misdirection, jargon-mongering, evading key issues, feigning disinterested objectivity, willful misunderstanding of other points of view---suggests that ... lacks both credibility and evidence.
