Echoing what I just posted in the other chat:
pStake should at least be added, since they are working with an automated delegation. So that is quite a no-brainer.
I would personally also like to see an exploration at the inclusion of QuickSilver to make sure we diversify even further. I am aware that they work with intent signalling and is more difficult in that perspective compared to Stride / Persistence, but reducing systemic risk should be a core topic imo, since we are talking about considereable amounts of funds here.
