Hmmm, but the "Used" field should give information about shm slots
occupied by configured balancers. Isn't the info (=0) wrong after a restart?

Concerning the long term statistical values I'm undecided like you, but
I think we should handle them in a consistent way, so "traffic" and
"elected" should either be both persisted or both reset.
