not at all as there is no Wayland backend in KWindowSystem :-) Let's care 
about Wayland when we have to care about it.

NetWM is a class which is X11 only. It will never be possible to use it with 
Wayland and it's not intended to be used for it. We will have to see whether 
we need something low-level for Wayland, too. I don't know yet, but such code 
will not start to be written in KWindowSystem but most likely first somewhere 
like libkworkspace. It will need some time to get used to the new world and 
that's something where we need to experiment first before going for public 
API.

Whether closing a window is something which will be needed for Wayland in 
KWindowSystem is quite questionable. If at all it's the taskmanager, no other 
client should be allowed to perform such a task. So most likely it will be an 
exposed interface between Plasma and KWin to allow Plasma to perform such an 
operation. Then I don't see much need to expose it in a high level API, if 
there is exactly one application which is allowed to use it.
