From my understanding, the security decisions around things like screen locking are the source of many of the pain points holding back X11 users from wayland.. Things like xtest(send input events from random sources), screen grabbing/video recording(allowing another app to see the contents of another window from a potentially different security domain), focus grabbing, input sniffing, are all difficult on wayland, specifically because they are serious security issues on X11, especially in light of a modern understanding of the risk profile.
Yes, many of Wayland's problems come down to particular ideas about security at the expense of functionality. But IMHO screen locking is a rare exception because the overly restrictive approach is actually fairly reasonable here, and the set of features to (not) implement is smaller.
