Not really. There's a parallel thread on the front page where everybody's talking about writing a browser engine in anything other than Rust is irresponsible, and ridiculous. And yet, no one's rushing to pick up Servo. There seem to be some projects in GTK and QT to embed it, but other than a handful of pretty niche browsers, doesn't seem like there's much use.

Nobody is using it because it's not ready to be used. Compatibility with web standards is nowhere near the level of browsers people actually want to use.

Writing a new browser engine at all is irresponsible and ridiculous. Doing it in anything other than Rust just makes it slightly more irresponsible than it already is.

I believe Ladybird is being ported to Rust as we speak.
