From what I can gather, the current API is mostly about CSS-rendered text, but we certainly know of web content that would benefit from having more information about font data, font features, and geometry data.

Yes, I have only been considering CSS-rendered text. I’m assuming enhancements to canvas text apis [1] and/or SVG would happen in parallel, though I think they’re both a bit farther along in extensibility. What we expose in the underlying font data or in the primitives John Daggett is suggesting would probably be shared.
