I've never seen a font designed with both serif and sans-serif faces before (though it's seemingly unclear whether the Aptos Serif variant shown in the article is going to make it into wide availability.)
Makes me wonder: could "serif to sans-serif" be an OpenType variable-font axis — i.e. could a font be designed to gradually "grow" serifs out of a sans-serif base, and to look good at any "degree" of serif-ication, the way modern variable fonts are designed to look good at any "degree" of weight?
What would a 30% serif'ed font even look like? Would it have little vestigial bumps only visible at large optical sizes?
