Comment # 5 on bug 1204658 from Stefan Hundhammer

In particular:


"Why Both Filters? Why Retracted AND Retracted Installed?


When experimenting with retracted packages, I always found it quite
disconcerting to know that there were some retracted packages somewhere, but
the filter did not show anything (because I did not have any of them
installed).

This view will very rarely contain anything anyway. It is there mostly to
reassure users that their system is not in danger, that they don't have
anything installed that we consider potentially harmful (so we had to retract
that version).

But a view that is always empty might as well just be broken; so it gives some
more reassurance to be able to see all retracted packages, even those that you
don't have installed. This view will normally also be empty, but as soon as our
maintenance team starts using that feature, users will hear about it and wonder
if their systems are affected. When they see retracted packages in that view,
but not in the "retracted installed" view, they can feel safe."
