To possibly simplify this a bit, consider that:
*) It doesn't hurt anything if a node has itself listed in its own MyFamily. You can just use the same MyFamily string in all your configs. Roman
Would that unknown fact be the reason so many MyFamily sections are botched?
With changing fingerprints through updating or VPS problems it has been difficult to keep up-to-date MyFamily entries unique to each relay. One list is much easier.
