Lots of bits of Servo use the FFI, but we've been replacing them as we go along with Rust versions. We did this so we could stand up a whole browser as fast as possible and then iterate on the important pieces first.

As an example, we used to use Netsurf's C library for CSS stuff, but now we have our own parser and style system written in 100% Rust.

I think it's a great approach, and I plan to whole-heartedly enjoy watching more and more of those chunks get whittled away as time goes on. I'd love to see a pure-rust spidermonkey replacement at some point!
