I think the council should be allowed to do so, if they can prove a package is dangerous/malicious.

And even though people are warned about the dangers of installing from the extras-devel and extras-testing repositories, intentionally dangerous software should be removed.

In case the maintainer of a package is aware of faults in his or her software, as described by Mentalist Traceur, and does not take action to fix this, these packages should be removed aswell.
