VESTS is there so rewarding SP via inflation can be done with a single change of value instead of adding differing values to ALL accounts that has SP according to the amount of SP on each account. I'm sure you are aware how it works.

If you want to abolish VESTS, do you have an alternative in mind that at least as efficient? Or do you also want to abolish rewarding SP via inflation altogether?

I believe regular users never need to care about VESTS anyway, the same way they never need to care about rshares. I believe VESTS is worth keeping.
