As of now its not a priority for solus because of the lack of support by proprietary drivers
Solus team said:
“It’s not a priority. Many users require use of the proprietary drivers (NVIDIA) which do not support Wayland in the context of Mesa/EGL, or X11 specific apps/functionality not present on Wayland.
While Wayland is an interesting new technology – we don’t consider it yet ready for prime time on Solus.“
