KDE allows some start feedback - the icon of the applications is moving up and down - which usually stops after some seconds. Not so on wayland.
Example: Have a mail in KMail with a link. Click on the link, Firefox opens in the background (this is different from X11, but OK) and the FF icon jumps up and down *forever* until one switches to Firefox. This is quite distracting while reding mails and opening links in the background....
