I absolutely agree that Grants Committee (GC) members should not serve on this panel, nor should Governance Solutions Engineers (GSEs) serve on the GC. Furthermore, I think it makes sense to ask the GC to operate the GSE Program multisig. In this way, there is a tight interaction between the two bodies which may benefit from one another. In utilizing working groups to tackle these problems, it makes sense that these working groups also help provide an added level to GC project evaluations by way of relevant expertise.
Overall, I see this as a huge benefit to the DAO, as we’ve needed the results of this kind of focused effort for some time now.
