I worked on the Aura side of the proposal for this with Tritium.
Aura is closely aligned with Balancer, is the largest holder of veBAL, and has over 3,500 unique users. During the current crypto winter engagement is at all-time lows, a system like this protects the protocol without sacrificing decentralization. The current system requires delegating veBAL voting to the Aura delegate or other protocols, which requires gas for users and harms decentralization for both vlAURA/veBAL. On top of delegates being inefficient, there are obvious conflicts of interest that come up where teams avoid votes, this model ensures 100% of votes are used, 100% of the time… once again further decentralizing veBAL.
Using 100% of AURA’s underlying veBAL to vote through snapshots further decentralizes both protocols and protects from systems like tetuBAL which are largely controlled by sole entities. For obvious reasons, Balancer holders and Aura Holders are largely the same groups. Not leveraging the full power of Aura’s veBAL makes governance much less predictable and at risk of being manipulated.
Keep in mind this is strictly for governance proposals as Aura has its own Hidden Hand bribe marketplace.
