--- Comment #6 from James Ausmus <james.ausmus at intel.com> ---
There was a recent email thread about this, here's Jani Nikula's response:

"We get a hotplug interrupt before the plug is completely out, while ddc
communication still works with the display, and we conclude we are still
connected. Moreover, the live status bits on the hotplug state have been
notoriously unreliable in the past, we've tried using them like three
times in the past, leading to regressions and reverts every time.

You can come up with all sorts of pathological slow plug/unplug/wiggle
cases. If you have a concrete requirement how slow needs to be okay, or
better yet write a test case for igt and chamelium, we can work with
that. We've proposed fixes in the past but they stalled because some
undisclosed unquantified test case still failed."
