I'd like to see one example of an article, or a class of articles, that would be clearly improved by being put in article-with-subsections form, rather than simply broken into a series of shorter articles.
I understand that you want an example, and I don't intend to make one. That was why I just mentioned potential power of section headings as loose idea on the tech list. Many encyclopedias have really long articles that are subdivided in this way. Making separate articles (without using subpages) requires that they can stand alone with just a brief introduction at the top. This is fine with [[Swedish monarchs]] or [[History of Poland]], which don't need to be part of [[Sweden]] or [[Poland]]. But "The Middle Ages" is a section heading in [[History of Poland]]. If broken out into a separate article, what title should that page have? Maybe [[Medieval history of Poland]]?
