The packages won't be removed altogether, they will be relegated back to devel and the maintainer has the right to promote again after they are fixed. See it more as repairing a wrongful promotion than anything else.

I am not sure new rules have to be issued as the patches clearly violate existing rules. Maybe we should set a rule that overclocking by default should be prohibited (unless user gives explicit permission), but that I think is common sense. The fact that overclocking voids the warranty should be enough evidence to the common sensibility of it.

Seeing the process backwards, if the community and the maintainer sees the decision to demote as wrong, it would take just a few days for the package to reach extras again.
