I really thought it was just one of the publicized rolling blackouts that would be over in an hour. If I thought it was going to be more than that, I would have gone out to drain the pool plumbing. Even that, I never thought it would freeze solid by 6:30am, but it was. Solid.
I too turned the breaker off to the pump before the power came back on. Our filter canister is cast aluminum and seems to be 'OK'.
I agree on your assessment.
