I'm very happy Servo exists but if they want, like, a working browser, it's no wonder they chose Chromium.

For comparison, from a recent Servo blogpost: "Servo can now run Discord well enough to log in and read messages, though you can’t send messages yet. [...] We now support enough of XPath to get htmx working.".

Servo has been in development for 7+ years and it's still not able to render modern web. Maybe it never will, since it's impossible to build a new web browser.
