> And yet, no one's rushing to pick up Servo.

Mozilla Firefox merged Servo's Stylo CSS engine into Firefox 57 in 2017 and their WebRender renderer into Firefox 67 in 2019. I guess you could call that a "pretty niche browser" even then but that's a stretch.

No one's rushing to pick it up because Servo was originally an experimental Rust project meant to incrementally replace parts of Firefox. Then Mozilla stopped funding its development, and only recently have people picked it back up again as an independent browser implementation.
