Someone on our last release thread on Reddit (https://www.reddit.com/r/rust/comments/1odnore/boa_0210_rele...) mentioned adding Boa to Blitz, which I think would be interesting to see as well.

We're looking into the next release potentially being a v1.0, so maybe that option is a bit more possible after that release. But at the same time, I think Servo spends a decent amount of time maintaining the `mozjs` crate, so who knows.

I can't speak exactly for the other maintainers, but for me, I mostly enjoy working on Boa and Boa related things (I've spent the better part of the last year and a half on the temporal implementation). I think it would be cool to have a highly performant and conformant Rust JavaScript engine. So that's my goal :)
