Probably I'd think KWin does not have to merge IM daemon and I hope we can make DBus proceses more secure.
Also I think virtual keyboards does not need to implement IM and they can enable IM with the shortcuts outside IM implementations.

Probably you have to support copy & paste between applications and support protocols between processes.

I guess just implementing Plasma Wayland with the current IM modules also will causes many regressions as GNOME did.
