I will never understand what is rough. Ive been using fedora kde for what ... 2-3 years now? More?
2 years ago there were some issues with nvidia, but that is fixed now mostly.
I use it for work, there is an ocasional hiccup, that gets fixed next reboot, something like a terminal not resizing just right but ... thats it?
People dont like change man, in the day and age when tech changes at breakneck speed, people dont like change
Those are terribly run enterprises. I work for a giant multinational that is widely considered to be obsolete tech-wise ... I'm on fedora 42 on my work laptop. The team responsible for vetting, security and customising the deployment was ready day one.
Its 3-4 people catering for the ~2-3000 users that use the os internally.
I get the need for stability and repeatability in enterprise. I'm a sysadmin for more than 20 years. That 3 year timeline could maybe move up a bit, even windows deployments are more or less up to date. Why would't linux be?
Lastly, the more resistance to wayland, the longer it will take for it to reach a level of polish to where even you would aprove of.
When the switch became inevitable (distros defaulting, dropping x11), I installed it, lived with its crappy issues back then, reported said issues and moved on with my day.
Edit: I will say, one thing I still hate about wayland is the sleep behaviour. The 2 x11 systems I still use work well for this, none of my wayland systems want to wake up from sleep nicely.
