I’m on their mailing list. They appear to have mitigating procedures under development.
AFAICT, they would prefer not to have to deal with it but they are prepared to do so.
One approach is that each field is imaged in several filters. A satellite will have moved between successive images, so a transient still stands an excellent chance of being detected. A problem, as I understand it, is that the calibration images (i.e. those without transients) will require much more care in their preparation.
