BIP-46: Restructure the Joint Balancer BeethovenX Deployment on Optimism

This proposal is just posted on balancer forum https://forum.balancer.fi/t/bip-xxx-restructure-the-joint-balancer-beethoven-x-deployment-on-optimism/4948 which is authored by several Composers and Music Directors

In addition to the Balancer forum post, some specific details for the Beethoven X side.

Modify the fee distribution for Beethoven X

Currently we allocate our 50% share of the fees as: 25% to match voting incentives, 17.5% to treasury to buy veBAL, vlAURA or auraBAL and 7.5% to maBeets gauges.

With this proposal, we only get 17.5% instead of 50%. We propose to allocate 10% to the treasury to buy veBAL, vlAURA or auraBAL and 7.5% to maBeets gauges.

This allocation will decrease our monthly spend for veBAL, vlAURA or auraBAL but on the other hand keep the incentives for the maBeets gauges at the same level. This poses no down side for maBeets holders and the treasury already accumulated the minimum vlAura amount (>0.2%) to be able to direct votes to pools.
