I suspect looking to sailing would get you the best answers as an outsider. Dyneema ropes are used for sailing but I don't know about the replacement rates, or if they are replaced preemptively for racing where the risk of an issue after some use is too expensive and replacement is cheaper. I have have seen lots of parachute or hot air balloon fabric offered because companies have a limited number of hours of use before they retire them.
