Samsung Open Source Group's engineers write about Wayland, Servo, the Linux kernel, Tizen, and Enlightenment, with practical how-tos.
Commenters cite it for Wayland network transparency (Wayland Over Wire) and for Servo's embedding support when discussing remote display and browser engines.
There is an RDP backend for Wayland: https://241931348f64b1d1.wordpress.com/2016/02/12/waylands-rdp-backend/
There is a SPICE backend:

There is the Samsung effort Wayland Over Wire (WOW): https://blogs.s-osg.org/wow-wayland-over-wire/
Apparantly, the Pipewire effort to make a high performance, low latency audio/video server will address remote display somehow too: https://blogs.gnome.org/uraeus/2017/06/20/fedora-workstation-26-and-beyond/#comment-6906
Processor power use scales with frequency as well. See [0], specifically the 'Low Memory and Power Devices' section, which shows power savings running 4 cores at lower frequency versus 1 core at max frequency. I think they eventually decided that running at max frequency on all processors and sleeping wound up being most efficient but that's my memory and could be completely incorrect.

I think it already does support CEF to an extent - no idea if it's enough

There's really very little standing in the way of network transparency: https://blogs.s-osg.org/wow-wayland-over-wire/
