Ubuntu tried shipping wayland on by default already and it was a clusterf* and made that release all but unusable. Wayland isn't ready for an LTS release yet.
FWIW I would like Wayland to finally take off, but each time there some random shit that's still broken despite 12 years of development.

Yeah, that. Not supporting ~half the video cards in the world sounds like a clusterf*. I know it's largely nvidia's fault, but at the same time, I have a lot of investment with them, and none w/ wayland.
