If I were a Boeing manager, I'd much rather deal with a temporary grounding than a third crash.
Corporate memory fades over time, engineers with scar tissue retire and MBAs pinch harder on pennies.
The 787 battery wake up call seems to have been treated as a one off without a deeper look into how that design snuck past the DERs.
Big difference between 787 battery issue and 737MAX Lion Air event. With the battery a subsystem component had a failure that was thought to have such a low probability as to not require consideration. With the 737MAX system the expected/assumed pilot response to a failure that was considered during design did not hold true. No pilot involvement with the battery failure consequences. Flight crew very much involved in the MCAS with errant AOA sensor consequences.
