Servo is not the old name for Gecko. Gecko existed long before Servo was started and Servo continues to be developed independently of Mozilla. It was a research project to develop a web rendering engine in Rust taking advantage of parallelization. The parallelization stuff mostly made it through the Quantum project several years ago, which did indeed help performance. That’s about it. As of right now, Gecko’s code base 55.4% C++, 22.6% JavaScript, 4.5% C, 4.3% Kotlin and a mere 3.8% Rust. If Servo had indeed been integrated into Firefox, over half of this would be Rust. 53.2%, if the current Servo repository is anything to go by.

I personally think it is silly to try to keep alive. If it was good Mozilla would’ve used it more. You can have your own take though
