"keep_screen_on_enabled" feature that is not documented anywhere

We discussed it here:
https://discuss.grapheneos.org/d/2352-screen-sporadically-doesnt-turn-off-automatically/14

Originally everyone thought this was some bug, but it turns out to be a feature that is enabled by default, and leads to unexpected dimming behavior (Screen can stay enabled for 10 minutes, ignoring screen timeout set by user in settings), the main problem IMO is that it is not explained or documented anywhere, not configurable:

This is due to "ScreenUndimDetector.java" and seems to have started with Android 12 December update.
If you undim the screen twice within 5 minutes, the screen is then kept on for 10 min.You can test this as follows:
Set the display timeout to 30s
Let the screen dim (but not turn off)
Brighten the screen by touching it
Let the screen dim again (but not turn off)
Brighten the screen by touching it
Now the screen won't time out on its own (for about 10 minutes)

Could you please just disable it by default, or maybe somehow make this behavior obvious to user (Add some checkbox to settings app)?
Patch that disables it in LineageOS (Although it doesnt look like it is compatible with GOS sources, I am not an expert):

Not sure if you are allowed to diverge from stock pixel firmware too much, but it seems this feature is also enabled there by default, and people are complaining:
