With guiding you're usually aiming for 5-10 minute exposures per frame. That usually results in each frame having at least several streaks. Sure, those are technically still short and can be cancelled out, but astrophotography is already challenging enough and has plenty of other noise sources without adding more fuel to the problem.

And that's now, when we're not close to the planned tens of thousands of satellites by Starlink above, and other vendors like Amazon only starting to plan their similar programs. That's why early feedback is important - otherwise the sky will be ruined in the best case for decades to come.
