Old Wall Street saying was 'Your first loss is your best loss'. Cutting losses is usually good policy.
That is not happening here.
Boeing and its suppliers are still building over 40 MAX airframes each month, at a cost of at least 2 billion dollars.
At some point, unless the aircraft has a clear date for return to service, that has to stop, because the money is not there. So there has to be political pressure for a solution, because a shutdown would be pretty grim.
How that gets balanced with regulatory oversight is murky, but nobody wants Boeing to go under either.
