Here in the grim darkness of the future, every install of a general-purpose OS better be shipping with at least one font (or collection of fonts that operate via glyph fallback) to cover every Unicode codepoint for every language that isn't extinct yet. (In other words, apps that expect to be used with any arbitrary language, including browsers, should not be forced to ship with a font just to ensure basic coverage). And then, once you have that system-provided codepoint coverage, you can make your font parametric in order to avoid needing to ship multiple copies of the font for different styles. It's not a perfect solution, but it's still pretty acceptable given the constraints.
