You could conceivably add an action to any context in the database - that's why we don't hide them. It's not safe to assume that because the projects you're working on don't include any actions for some context, that they will never include an action for that context. ("Active" means "this context could have actions, in other words.)

I could see adding an option to perspectives that would mark some set of contexts as on hold in that perspective - I'll write up a feature request on that and we'll consider it for a future version of the app.
