You mean requirements gleaned over decades of aeronautical and crash research?
I'm pretty sure the requirements are fine, but the process is not streamlined and hence avoided whenever possible.
You don't get to stay in business in a regulated industry with an attitude like that. What's next? Medical device manufacturers cutting corners because the regulations are too onerous? Regulations create a level playing field: all entrants get to abide by the rules. Or at least, that's how it should be. The FAA turning a blind eye here is as much a part of the problem as Boeing.
