I would like to see a Call to Action and Call for Help category 
However I don’t see how they relate to governance. I’d rather see those as sub-categories in the Workspace category, for instance.
I can imagine that adding them to the governance category could be an informal way to give those categories more weight, to encourage readers to pay attention. But since there is no way to explain why they belong to the governance category it may also have the opposite effect. Readers would rightfully ask about the rules to to follow to publish a call … but there are no rules, it is up to each individual. And then they would ask why it is in the governance category since there are no set rules to publish such calls. Do you see what I mean?
