    This just makes a note that randr won't make outputs disappear
    dynamically.

+1.5.2. Clarification of Output lifetimes
+
+With dynamic connectors being a possibility with the introduction of
+DisplayPort multistream (MST), a lot of RandR clients can't handle the
+XID BadMatch when a RandR output disappears. This is to clarify that
+going forward the X server will not remove outputs dynamically,
+just mark them as disconnected.
