I think it's important to separate the consequences of this stuff on imaging and scientific work - which I think are minimal - from the aesthetic experience of a dark night sky.
Distinctions are very important, well said.
However even now it's not really hard to capture satellites with what one may expect is not a "likely occurrence":
(for ex. video of a trio of satellites crossing the path of a pair of satellites)
The "perfect storm" of unhelpful confluences of a key image acquired while a pass/flare occurs will ___-fold increase when you up the number of LEO satellites by the scale these mega-constellation anticipate...
Processing stacks of long exposures for a pretty picture is different that some other astronomic imaging methods:
meteor shower images
exoplanet candidate measurements,
PixInsight scripts won't immediately solve the issues of processes where momentary captures that don't have luxury of stacks is needed....
and this will not only be an issue for optical imaging, but for other spectrum types (like radio astronomy) as well....
Not saying that we can determine the degree of impact yet and there are usually work-arounds,
but what happens when the one-time glint off a potentially hazardous asteroid is approaching the Earth and at that very moment a satellite passes through the view and hides the asteroid's optical signature and it so happens to be in a position that it otherwise hides from detection until it's too late............
So there is also a distinction between normal day-to-day operations, compared with the increase of "perfect storm" occurrences that then might ruin important data collection....
