I don't know if this was the reasoning behind Cinder's system, but I 
know some people object to procedural -2 because it's a big hammer to 
essentially say "not right now". It overloads the meaning of the vote in 
a potentially confusing way that requires explanation every time it's 
used. At least I hope procedural -2's always include a comment.

Whether adding a whole new vote type is a meaningful improvement is 
another question, but if we're adding the type anyway for prioritization 
it might make sense to use it to replace procedural -2. Especially if we 
could make it so any core can change it (apparently not right now), 
whereas -2 requires the original core to come back and remove it.
