alt Hacker NewsServo is slowly but steadily getting there. The thing with Servo is that it's highly modularized and some of its components are widely used by the larger Rust ecosystem, even it the whole browser engine isn't. So there's multi-pronged vested interest in developing it.
Moreover, Servo aims to be embeddable (there are some working examples already), which is where other non-Chrome/ium browsers are failing (and Firefox too). Thanks to this it has much better chance at wider adoption and actually spawning multiple browsers.

Alas not nearly as modularized as it could be. I think it's mainly just Stylo and WebRender (the components that got pulled into Firefox), and html5ever (the HTML parser) that are externally consumable.
Text and layout support are two things that could easily be ecosystem modules but aren't seemingly (from my perspective) because the ambition to be modular has been lost.
