Sadly, Servo more or less halted when Mozilla laid off people in 2020. It only really started back up in 2023 when they secured new external funding. That said, I don't think Servo intends to be a fully-fledged Browser like Ladybird. While LB intends to be a car, Servo plans to be a great engine, but only that.
...on the other hand, Ladybird's lead dev seems like trouble. So maybe I'd rather wait for a Servo-based browser instead.
It's a little complicated, but it doesn't look good. If you're interested, I wrote a comment about it.
