Servo was where the most interesting new Gecko features were being developed. It only makes sense if Gecko is considered no longer a worthy investment.

That statement about Servo seemed more true before Servo work shifted to focus on XR than after. Though I still think there was plenty of interesting Gecko work done in Gecko -- probably depends on what you find interesting.

I don't think the focus on XR changed anything. It just meant that some of the team was doing XR stuff. (I avoided trying to get sucked into XR specifically because it wasn't as interesting to me)
