I doubt very much
DVC wants nor will nix "renting" as a whole, not without completely overhauling the point banking policy and probably the conversion systems as well. (to Disney cruises or Interval Int) otherwise it will become restrictive to everyone when the goal was to curtail commercial renters. It should be very easy for Disney to identify those that are commercial renters. They have all the data they'd ever need to easily see who does it for "gain" and who does it to not lose point value.
Some changes may come to the policy of renting but nothing that I'd imagine impacts people looking to rent unused points to prevent loss.
As for the OP, I'd get the extra, maybe not 80 but something. Just to act as a buffer for when timing doesn't allow the economical reservation. Renting them, I suspect will always be a thing.
