It's not just anyone, it's the folks at Igalia. I think people disregard Servo since it's no longer under Mozilla but Igalia aren't just random contributors picking up the slack, they're browser experts that also work on Chromium.
Personally, I disregard Servo because I've been hearing about it for 10 years. I'll start paying attention again when they remove the "don't log into your bank with Servo" warning.
"These pre-built nightly snapshots allow developers to try Servo and report issues without building Servo locally. Please don’t log into your bank with Servo just yet!"
