When a replica falls back to RS102, is it safe to try to fix that automatically by resyncing the DB? Administrator intervention is in most cases a good thing, so I'm just testing the water. I'd imagine there's a worry about data corruption here that I'm overlooking.

Perhaps this should be an option? (If I hit RS102, resync from scratch?) We missed a few backup replicas because we don't really monitor them, and it would have rocked had they fixed themselves.
