The repo seems rather unmaintained and a couple of security related issues are not addressed for years.

Is this still intended to be used eventually or does it have a successor?

Nobody is actively maintaining it.

Do you still accept pull requests?

I suspect it will be more effective to fork. I don't think anybody involved with Servo these days has any real experience in this code, so reviewing any changes would be challenging.
