If the flare is that late, there won't be time to do anything about it. Even if you wanted to, which you don't. A transfer (or ambiguity) of control in the flare is not a place to be. Anyway, a hard landing for a late flare is not a "serious" breach of safety. You say that a record would go to the fleet office, however I suspect a "hard" landing incurred from juts a late flare would be nowhere near hard enough to warrant such a report. It may feel hard to all on board, but I doubt the machine would be bothered.
