I also do not agree with the Wayland is inevitable sentiment. There are non-systemd distros, there will also be non-Wayland distros. The idea is that only those things survive which are pushed into the ecosystem by the cooperate bullies is wrong, otherwise Linux would not exist.
The Linux desktop was essentially fine already two decades ago and instead of the needed refinements, bug fixing, and polishments, we get random changes in technology after the other, so nothing ever really improves but we incrementally lose applications which do not keep up, break workflows, sometimes even regress in technology (network transparency), and discourage people from investing into applications because the base is not stable. My hope was that Xfce4 is different, but apparently this was unfounded.
