I have been following this issue since commit
30d974bf5c02a1367291fbb6fa17a182bb7974b7 breaks EXWM (the Emacs X WM),
since the first operation is resizing the frame to full screen.

>From this last message I understand that the issue is not going to be
addressed, which means that EXWM users can't use Emacs master branch.

Is my interpretation correct?
