I've been thinking of how browsers are eventually proving to be bad at complex text rendering, like for a word processor. You either have to make do with mimicking DOM like a text layouting engine or use browser canvas APIs - both of them locks your codebase into a single target (the browser).

The right way feels like using a cross platform text rendering engine like Skia (or this one, if it could be compiled to WASM and somehow made to write to a browser canvas)

These projects are important for that future. The one where word-processor like apps can be written cross platform by using libraries like these.
