if the load bearing core is miniscule and light you have plenty of mass and radius available for abrasion resistance, handling properties, etc ...

Yes, but we are there already in many applications where we need to pad the core for abrasion and handling. Making the core even more smaller makes no big benefit - unless it is substantially cheaper than the competition.

And to be clear, I believe there are multiple applications for higher tensile strength fibers. I just can't see that many applications where thinner ropes than current technology produces would be a game changer.
