The shift away from X11 means no more forwarding X11 applications over ssh, which is slow at best and buggy and insecure at worst. A small price to pay for eliminating tearing and actually-secure screen locking. There are valid criticisms of the move to Wayland but I don’t really think this is one of them; if you really need remote access to graphical applications you almost certainly should not be using X forwarding.
