https://en.wikipedia.org/wiki/Special:ApiSandbox#action=mobileview&format=json&page=Main_Page§ions=all&prop=text%7Csections§ionprop=toclevel%7Clevel%7Cline&noheadings= Normally noheadings=true prevents 'duplicate' headings - one in content and one as part of metadata. However, since Main_Page is never sectionized, specifying noheadings just scrubs the headings, without making them available anywhere. noheadings should have no effect on Main Pages - noheadings kills section headings, and since there are 'technically' no sections on Main Page (everything is returned as one blob), it makes no sense.
