Say, it would be nicer, when role references were removed
with the role.

However, Zope does not maintain a data structure that would
allow to efficiently find the references to a role.
A brute force search operation would be necessary, which
might be very expensive.

In several such cases, Zope simply does nothing and leaves
it to the application to clean up state when it thinks
it need to.
