Living as I do I the land of the opportunist attorney it's interesting to learn that mandatory sea belt replacement intervals (and other such nonsense) are supposedly driven by fear of lawsuits... all the while secure (literally and figuratively) in the knowledge that the belts on my C of A aircraft were rewebbed 32 years ago. They are still just fine and it gets through annual inspection with no issue.
That said, the best solution for 'maintenance programs' for light aircraft is to get rid of them and free the mechanic and owner to figure it out real time, based on physical inspection, protecting their own real time interest in safety. Part 91 does just fine that way, and always will.
What you're describing is disconnected, inexperienced bureaucrats desperately justifying their role by creating and enforcing unnecessary law. That's the beginning and end of the situation.
