AFAIK aircraft and jet manufacturers actually have little or no interest in contrails & that is likely to remain the case unless politicians decide that contrails are actually a contributor to global warming worth taking some action on.

I seem to recall a few years ago a RR engine was pulled off a wing having achieved the amazing life of 20,000+ hours of service - which is, of course, just flying hours and not maintenance & taxying (at least I don't think it includes taxiing) - but jet engines used to be routinely overhauled at 6000 hours operation. Tehse days the various modules are more likely to receive their own overhauls rather than the engine as a whole, plus there's all the fuel related components such as pumps, meters, valves, etc all of which are cosntantly wearing and will have their own overhaul/maintenance lives as determined by how they wear.
