This. Given the failures, admissions and scrutiny the FAA is now under there should have been no option for Boeing to continue to band aid the airframe. Boeing should have been forced to pull the plane as "737" and recertify it as a new airframe from scratch. But why weren't they? My guess would be because Boeing would have to eat very large losses of dealing with customer lawsuits (bought an airframe that wasn't certified), would lose all future revenue as customers would cancel orders and buy airworthy competitor options, and Boeing would be forced to say they were wrong.
Regardless, this still seems like the right path (recertification). It seems the FAA is still being strong armed by Boeing. Why? Put these people in prison. Shut the 737 Max down. Make Boeing face the music. They need to fail to get the point, apparently.
