Yes, that's what I'm referring to. They could build on that, or they could write something their own in Rust. But I'd think building on Servo would be fantastic.
I know about servo. It was pretty much a dead project until they joined the Linux fondation last year and started getting some sponsorship. Since then, they being doing pretty good on there own with personal donations rising by around 20% each month, reaching more than 2000$ monthly. Wish them all the best!
