> Moreover, the fontations platform, which is the Rust framework Oxidize is producing, will unify font compilation and consumption, reducing the number of places new font-format features need to be implemented from three (FontTools, FreeType, and HarfBuzz) to one (Fontations), which would reduce development cost and overhead.

Will FreeType and HarfBuzz remain supported as C/C++ projects long-term, I wonder? Asking as someone who depends on these and doesn't want to introduce a dependency on a Rust compiler :)

Anecdotally, I notice a lot of game developers avoid FreeType and Harfbuzz entirely, instead opting for much worse text rendering in the form of stb_truetype.h only (Dear Imgui uses this, for example) - which 'is nice because it is a single header C file' but sucks with international languages; many people use SDFs for similar reasons.

I think the proposed move to WASM fonts, if done right, could make it easier to reduce the amount of code people need to render fonts (if the WASM font does the heavy lifting, and a small C program could render it) and alleviate this trend of people not using a good text rendering stack
