At then end of the day, a great many people, firms, and governments are finding that they care about the increasingly fragile set of design, engineering, and control kludges Boeing have had to strap on to the 737 airframe in order to 1) accommodate the initial low-clearance landing-gear design (intended to facilitate cargo handling), conflicting with 2) greater demands for efficiency through 3) ever larger ducted-fan engines 4) mounted ever further forward, and higher, on the wing resulting in 5) AoA control issues under high-throttle conditions answered by 6) a pilot control defeat countermeasure which has resulted in multiple crashes and the loss of over 300 souls.
The customer doesn't care about the implications of design decisions, until they do. Clean, simple, stable, predictable, maintainable, modifiable designs deliver quality performance over a longer period of time. Complex, kludgy, unstable, unpredictable, tightly-coupled, unmaintainable designs will eventually bite you in the ass, or scatter your body parts over the landscape.
The fact that the implications aren't clearly discernable in advance does not mean that they do not matter.
