Keep domains of child circle in parent circle?

Hello Advocates,
Our community is wondering if we should stop keeping domains of child circles listed as domains of parent circles. The argument in favour of doing so is, essentially, that it is easier to look up all the domains that the parent circle is responsible for if all are listed as domains of the parent circle. The argument against is that if the parent circle keeps those domains, they can overrride decisions of the child circle. This has not occurred in our community that I know of, but some of us see the potential for that and other forms of undermining, such as the parent circle making a policiy decision about a child circle’s domain.
