	Yes, they are N more things that can interfere with astronomical
observations.  But I don't think it makes so much difference whether a
satellite flashes or not.  A +8 mag satellite can potentially interfere
just as well as a -3 mag satellite can.  The fact that there's 8000+
objects in orbit contributes to the problem more than anything else.
Unwanted satellite streaks probably aren't all that rare these days.  I
wouldn't be surprised if projects like SpaceWatch pick up satellite tracks
all the time.
