It is currently easy to break packages by updating a package that is
inherited from. You have no way to know about that relationship by simple
inspection, and is not discoverable by current tooling either. So I also
believe that it would be useful to at least be able to list them. One place
where this becomes painful is in bootstrap chains.

Do you think this can be achieved somehow without complicating
implementation?
