I think we have to be really careful with making a step like this. As others have mentioned, it will be hard to relay our 3,3 message on a third party site.
I am definitely against custodial staking as this should be kept inhouse. I do see an opportunity in the bonding process being managed by a CEX or third party as this surely will increase the revenue of the treasury, however, whoever we partner with needs to work with our DAO to create the same message of 3,3 on their portal/site and I think that is where the problem lies.
I think the market will come to us, so any partnership we do agree on should be very lopsided in our favor!
