[Proposal] Allocate BAL to AAVE/WETH Stakers

This proposal also appears on Balancer's forum.

As part of Aave’s Safety Module, an 80/20 AAVE/WETH pool was created which has since grown to be the largest pool on Balancer v1. The creation of this pool, along with the dual incentives of BAL + AAVE, established a strong partnership between Balancer and Aave. That partnership has continued with the ongoing development of the Aave Asset Manager (AM), which will be the first AM deployed on Balancer v2.

Motivation

Given the critical importance of the Safety Module, Aave requires additional time to migrate their pool to Balancer v2. In order to preserve the allocation of 12,500 BAL per week the pool was receiving before v2 Liquidity Mining started, we need to give Ballers the authority to allocate BAL to the 80/20 AAVE/WETH pool on v1.

Specification

The Ballers will initially allocate two Tier 2 slots and one Tier 3 slot for a combined 12,500 BAL per week - this will be reflected in the next weekly vote on the Baller-only snapshot. Going forward, the Ballers will have sole discretion to adjust this pool’s allocation as they see fit. The BAL allocated to this pool by the Ballers will go directly to users who have staked BPT from this pool in the Safety Module, meaning if you enter this pool and do not stake in the Safety Module you will not get BAL rewards.This pool will no longer be included in the v1 reward calculations.

Note: Aave has agreed to a three month migration deadline. BAL rewards will be provided during this time period, though not necessarily at the full 12,500 BAL per week. Ballers can choose to lower the amount if they deem it appropriate. At the end of three months, if they have not migrated to v2 then BAL rewards for their pool will end. The migration deadline will be September 20th, 2021.
