Those are the sum total of in-body elements that need special handling
to work properly.  The only other elements are the page-structure
ones, which I don't believe have any use-cases, as there's only one of
them for <html>, <head>, and <body> and they already exist, or they're
obsolete in the case of <frame> and <frameset> and don't need to be
handled specially.

SVG and MathML fragments need to be handled properly, though, as
they're currently misparsed as HTMLUnknownElement.
