I am in favor of this proposal and will vote “Yes.”
The benefits of JIP-25 outweigh the drawbacks imo, the main drawback being its advantage for older validators, a concern others have rightly noted. In the short-to-medium term, this will likely drive many validators to lower inflation and MEV commission to zero, ultimately benefiting JitoSOL users and holders, and potentially increases geographic distribution if relevance of TVC decreases. While validator age will be the hardest metric to achieve, it both rewards longevity and incentivizes proper operator behavior over time.
This shift should reduce the MEV blacklisting burden on Jito, the Solana Foundation, and other contributors, while also providing clearer visibility into validator history, whether that involves sandwiching, timing games, or other malicious/anti-IBRL behaviors. Tying incentives to validator history also makes it harder for bad actors to repeatedly re-enter the set under new addresses. Lastly, a complete validator history could support future proposals such as JIP-XX on direct staking. I have no strong opinion on TVC serving as a tiebreaker for validators of equal age.
