I feel like it's easier to just uniformly reduce the value of rented SPS by some number, e.g. 25%.
I also wouldn't want to treat delegated SPS negatively, firstly because it's used for new player onboarding and secondly because many of us (including myself) use it to delegate to our alt accounts. I don't want to have to distribute my SPS just because of this mechanic, seems unnecessary.
To be honest I'd rather not make changes to rentals for now. There is new utility coming to SPS soon - let's see if that impacts demand and the rental market before we make a decision on other things.
Also if we had a bid-ask market for SPS then you'd see prices go up as SPS owners could list it for higher and, in all likelihood, people would take those prices. I.e. get SPS owners to anchor the price, rather than the other way around. To me doing this and adding other utility to SPS is a better "fix" than trying to "taper off SPS rentals".
