QPlatformSurface relates to the platform window, not the wl_surface. The events are already emitted by QPlatformWindow on create/destroy.
To preserve compatibility for a previous KDE version it was faked to emit the events when the wl_surface is created/hidden to keep behavior. This is no longer necessary, and it has caused multiple errors, the latest being a crash when switching between sub-menus with the Sway compositor.
[ChangeLog][QPA plugin] QWaylandWindow no longer sends fake SurfaceCreated/Destroyed events. Use expose events to be notified when a Wayland surface appears.
