Flatpak packages still suck at integration without breaking something in the core app. They’re really great for bleeding edge and cross distro support tho.
Wayland still can’t do all the cool tricks X11 can, so it’s not like it’s really being forced upon anyone beyond X11 losing on potential major updates which is unlikely.
DEs are willing to switch to Wayland given that it is either equal or superior to X11 which is still not the case for several scenarios and applications.
