Good design practice requires a failure modes / criticality analysis (FMECA), and a good analysis will consider historical known failure types. Not just those required by regulators, but ones that (for example) could taint the reputation of the product or the company.
For example, a modern propeller design incorporated features that lost sight of lessons learned over 6 or 7 decades. As a result, a regional airliner augured in 20 years ago. Neither the designers nor the FAA had retained the corporate wisdom to prevent the design error.
