This seems to have shortened the duration of previous reviews. I assume that Blue Origin and others also have far more bandwidth available than was the case in the last millennium.

There have been FAA investigations after many of the SpaceX Starship test flights. Also a few by NASA. I have yet to hear credible concerns about their integrity.
