That is out of date, yes. It was turned on in bug 1701977.

Edit: Actually this is a little incomplete. It is still turned off with XWayland in late beta and release. So unless the MOZ_ENABLE_WAYLAND=1 environment variable is set, you won't get WebRender by default. I will need to review why we didn't ship with XWayland yet -- there were a couple of bugs (e.g. bug 1635186) but I don't know the status of them offhand. Expect to see movement here within the next few releases I would say.

Thanks for answering my question even though I posted it a day after this thread started.

I'm glad to hear that. One of my computers is actually using Wayland with MOZ_ENABLE_WAYLAND=1, but I haven't actually checked if it worked yet.
