Why not just consider the shared set as an own family?

The theory is that, if either operator's infrastructure were compromised or hostile, they would be a danger both to their own relays and to the shared relays.  Thus, you wouldn't want to use a shared relay in the same circuit with _either_ operator's non-shared relays, but it would be okay to use either one of operator's relays in the same circuit with one of the other operator's relays.

And that maps to a situation where each operator has their own relay family, and the shared relays would belong to both families.
