As I understand things this change was triggering a number of internal LDVS displays to not initialise due to broken lid detection leaving users with no display at all. The sheer number of negative quirks being applied to work around these cases lead to an upstream decision to revert the whole change as a bad approach to the issue. We are working on the assumption we would see a similar balance of bad initialisation, though the expected behaviour worse case was that some closed displays would be incorrectly enabled.
It is unclear why you get no output on your external display if it is connected on reboot.
