And that was my point. You were blaming the patch for making you aware
of existing behaviour that results in utter confusion, for as Alex
points out there is no sane way for userspace to handle the unknown
connection status from the detection routine. As such it is probably
better if that was handled internally as "result indeterminate; do not
update current detection status" which is the behaviour of some of the
drm helpers but uniformly. If that were true, then userspace would
continue to be told that the connection status was disconnected until
a monitor was plugged in.
