Valid question.
It depends whether you're imaging or just enjoying the visual side of things. For my part, I am an imager and that means fairly long sessions with many long exposures. For an example, assume a single OSC session on one target with, say, 40 x 5 minute subs -a total of 3 1/2 hours or so; most people would aim for more - particularly if you are doing imaging with filters. Even if you are doing longer or shorter individual exposures, the total integration time is more or less the same. It would be 3 to 4 times greater if you are using flters. So for NB or LRGBimaging, factor in 10 hours or so of tital time - and possibly spread over multiple nights.
The chances of multiple satellite passes follows the same pattern. Of course, the more satellites there are, the more likely you are going to have to reject multiple exposures. That has become a very common experience for me these days.
The region of the sky also has a bearing. satellites tend to inhabit either polar or equatorial pathways so the more you try to image in those zones, the higher the proabaility of ruined subs.
I'm not a fan, I'm afraid. I see greed eroding the night sky.

) I can imagine this thing becoming a massive issue for photography.
Oh and simply relying on kappa shchmappa blah blah and thinking it will be 10 years before its a real problem, is just not how it is...it's pretty sad really...nutin much we can do about it now either...
