I think we misunderstood each other. Running balance with swap disabled is not a problem. I have just done it, and as you predicted, many more blocks were identified for balancing. However, I cannot disable swap permanently. If I am planning to migrate away from a swap file on the Btrfs volume, then I need to resize it to make space for a separate partition for swap. I was concerned that the super mismatch earlier discovered might make it unsafe to resize the partition.
