If you want consistency, you only need to convince everyone to switch to a single font renderer (e.g. freetype). That won't happen, though, because OS font renderers have quirks that cause them to render the same things in subtly different ways, and users have come to unintentionally expect those quirks. Even if rendering is 'better' in one app.. if it doesn't match the others or what the user is used to.. then it won't 'feel native'.

Maybe if what freetype is pushing for (fonts are WASM binaries) continues to take hold, and encompass more of fonts, we'll find more consistency over time though
