Hotplug-aware userspace will disable the pipe on unplug event so the implicit modeset shouldn't happen. Apparently, there are still some questions about power management that need to be answered. >From an IGT test point-of-view, I think I'd still prefer to have one test for the legacy behavior (skipped on MST and on ICL USB-C), and other tests doing the Right Thing.
