I should clarify that I speak only of English and general web content CSS. I’m happy to disqualify 4 and 6 on those grounds (you decide which grounds I use for Fraktur!).

As for 5, I’m not convinced letter-spacing is the right tool for it: at those scales I’ve tended to prefer condensing or expanding the text, glyphs and all, which you can do in SVG. But I will allow it as a place where very careful letter-spacing use with kerning and ligature control can be acceptable.
