I like this idea. @Aro had mentioned it in his list of things to explore in 2025, and I was supportive of it then, too (Jupiter DAO: Things we should explore in 2025 - #2 by WTP). I think the Helium DAO has done this quite well, as users are able to read about each of the “Delegates” (every Delegate has their own profile), and users are also still able to vote themselves if they wish, with their own vote superseding the Delegate’s vote if there is a difference.
One thing I would add to hopefully address the concern of centralization would be a cap on the voting power a single Delegate could accumulate. Perhaps 5% of the total staked JUP. I am not as concerned about centralization as others (this is more of an efficiency point, and not a centralization point - the people delegating are still individuals, so having their votes just more efficiently get tallied through a delegate of their choice (this is a decentralized decision, as well - no one is forcing them to delegate)), but this cap should help address this concern nonetheless. I think 5% is a good level, but am open to feedback on this level.
