The relevance to this discussion is that the manufacturer seems to have had an incentive to look into the question of screen rotation in the different raspberry pi models, so their installation instructions at https://www.waveshare.com/wiki/7inch_FHD_Monitor provide some insight on how it is expected to be done. For Pi4 that seems to be by using the screen layout editor in the preferences menu. For Pi3 and earlier, it seems to be done with the line in config.txt. I had assumed that for the Pi4 the GUI configuration was just a convenient alternative to editing a text file that is read at boot time. But it now seems that perhaps the menu option exists because the old boot time functionality is no longer supported.
