OK, that clarifies things. Thanks.
So, essentially that means that you need to set all ancestor levels
to something at least as strict as the intersection of all the
permissions on lower levels to avoid exposing something through an
ancestor which is restricted in a descendant. And you'd better
trust the owner of any table you extend, because they can bypass any
attempt to restrict access to the table you create which extends
theirs.
I hope those security implications are well documented.
