Unfortunately the LSST sensors will be extremely disturbed by blooming from bright reflections from satellites. With the exponential increase in satellites projected in the coming years a non-trivial amount of observing power of this amazing instrument will be lost.
Unfortunately once there are enough satellites there will be trails crossing most of the sensors. (The projected densities from starlink and oneweb are truly staggering)
