Doh, yes. You are right about that.

To be honest, I find subconninfo quite useful to check where a
subscription is getting its changes from, so I'd rather not touch it.
It looks as well a bit overkill to just create a new view on an object
type non-superusers cannot even use... There are already 1 view and 1
system catalog related to it, so I'd be of the opinion to let it fail
silently with a permission error and keep it as an empty list for
them.
