> What would Servo bring to make web a big jump forward for us users

The biggest advantage would be having a memory-safe browser engine.

> but what value would Servo exactly bring to users and the web after all the engineering effort?

Servo was a much more modular effort.

1. we would get a lightweight (modular) electron alternative. This would have helped rust gui ecosystem a lot, just like wgpu helps rust gamedev scene.

2. Probably have more variety in browsers as everyone can now reuse servo components to make their custom version of firefox. Imagine all the linux distros which reuse gnu/linux, but have their own philosophy of package management, updates, mutability etc.. We could have had the same sort of varieties in browsers for different usecases.

Same selling points as Chromium originally: faster and safer. The premise of Servo is that it'd make better use of multicore and would be safer because it was written in a memory-safe language. For modern users the big one is probably battery usage, though, which Safari excels at but would be harder for an open source player that has to support every device.

Wasn't it just using WebKit initially? IIRC you could actually use Safari on Windows back then.
