Lets not even talk about trying to use Wayland in a VM desktop -- Even Firefox/Chrome don't render properly.
I'll try Wayland again this next semester, see if anything has changed.
But RHEL didn't even set a date for removing Xorg support so it will probably stick around for a long while.
For example, I still use pidgin for all my messaging (even with Slack and our own custom protocol). In xorg, I can set my pidgin buddy list as a Utility Window, make it sticky, below all windows by default, and skip the taskbar. This makes the buddy list not show up in my alt-tab or as a running application (doesn't show up in the gnome-shell overview). Then I have a simple script using wnck to raise/lower the window using a hotkey, which gives me really quick access to my buddy list and chats.
_Some_ of this is possible in wayland, but not everything.
I also haven't found a replacement for devilspie for wayland, which I use to set a bunch of default properties on various applications, like size, virtual desktop number, stickyness, and so on.
Both of these things are really essential to my daily flow and are going to be hard to give up.
