Have a read about Servo, it is binding with SpiderMonkey as JS engine.

Is there some chance, that servo decomposed from SpiderMonkey? If it is not, I don't think anyone can tell difference between firefox and other browser use Servo.

There's a lot more to a browser than the JS engine. And in general, we would want all of the browsers JS engines to be essentially the same. I think starting with an existing engine is the most logical approach

You say until there is a CVE found.

True but at this point of time, Firefox and Servo are using the same CSS engine, same JS engine and same compositor and rendering engine.

They plan to abstract it (work is underway) to make it even possible to use chromium's js engine. https://www.phoronix.com/news/Servo-JavaScript-Engine-Modula...
