@gosuto-inzasheru we would like to queue this to snapshot today. Can you do an initial review before that? Thanks

Given fee helper v2 is in the works this needs more clarity: balancer/balancer-deployments#309

LGTM!

Necessary governance permissions are in place; only one pool is being added to one set (BAL V2 / mainnet / wstETH-AAVE). Assuming initial manager is correct, although the set can be restored if required without governance by the maxi omni.

New sets can be created by the maxi omni later on without governance intervention.
