This option makes multiple references to RC and non-RC bugs based on actions of the policy editors.

It's my understanding that determining if a bug is RC or not is a Release Team function, not the policy editors.

Would it be better to use something like 'severe policy violation' (and it's opposite) than Release Critical?
