Well I never mentioned Linux. I mentioned a non-Unix Unix and two non-Linux Linuxes. They could be Windows CE under the bonnet and you'd never know.

Brian Kernighan on the name "Plan 9" (possibly-apocryphal anecdote):

The other interesting point was that he felt like some gratuitous changes in Plan 9 were done at too low a level -- the system call level -- which made it difficult to bring along imperfect but useful code. But that ties into why the name Plan 9 was chosen. Because the most characteristic thing about the movie is its total lack of continuity.
Possible worst take here.
Applications don't *have* to send that metadata - I would assume. Your window manager doesn't have to use it if it is present. *And* it could prove useful to other window managers in any given paradigm.
Certainly the yet-to-be-invented paradigm where the window manager uses "AI" to learn your preferences could do with all the information it possibly can.
