I heard that in a world based on the Wayland protocol, applications implement the window decorations. If so, I'm interested in how we can expect consistency; and eg. moving the window of an unresponsive application. This could well be a misconception, which is why now seems a decent time to ask. These seem to be good qualities of X. Wayland has been a number of years in the making, so I have somewhat lost track of my source of this information. Edit: Apologies, I did read the fine article. It appears I must have skipped a section.
