I like it, It gives an incentive for people to stake and a further one to vote or delegate.
I wonder if placing a cap on delegation makes sens (i.e. if a address has more than x% of circulating / staked tokens delegated they can not accept more delegates). Then whales can vote their entire stack, but they can not add further delegated votes (so, Set can DeFI pulse could vote with full [unvested] tokens, but not get further delegates - Obviously individuals linked to either organisation can be proposed as delegates, but they would be seen as separate to their employer and so attract delegates on their personal reputation.
