The false default forced every op-node restart to walk back to the finalized head
before driving the EL. On nodes whose derivation lags days behind their serving
gossip head (hashkey us-40: 510k blocks / 12 days), that froze the EL for hours
while dRPC de-routed the sole US provider. true resumes at the unsafe head in
minutes; safe/finalized still verify and catch up in the background. ronin
already ran true per-chain (same lesson); xlayer keeps its deliberate false pin.
