Why would it increase their security? They (Neutron and Stride) are already secured by the same ATOM stake that secures the Hub, give or take 5%.
I think the vision of ICS has always been permissionless, and the Hub has always been quite conservative about what we put in our blocks. I don’t really want any random chain team being able to spin up a chain that writes to our blocks, but I don’t mind them paying the Hub to secure their blocks.
I guess? To me, it sounds like frustrating redundancy that bogs down the provider chain’s state, but I guess I’m much more used to ICS than I am to Eth or Bc L2s so of course I have biases here.
Hub state migrations already sometimes take an hour or more during upgrades and I really would not want to add more state that doesn’t directly serve the Hub itself.
