For me a no-go for wayland is no support in LXDE and Xfce, which are very good lightweight out of the box user friendly DEs. There is LXQt and Xfce initiated the migration but until then it doesn't worth. Other hurdles are less important like multiscreen, multi-seat, Nvidia.
I don't believe this is true. It certaintly uses less memory out of the box and unlike Gnome, most of the optional extras are easy to disable or uninstall.
