`Historical Figures` is very similar to the value `Historical Forms`, which can cause confusion in localization. While Historical forms is the only valid value at this time, it will be more accurate and create less confusion to name this field `Alternate Glyphs`, which is a better analogue to the underlying `font-variant-alternates` property.
