I don't think there should be any restriction on what you can release as a satellite other than that it should be limited to core provinces and provinces where the nationality has say 25%+ of the population, and it should have to be one contigous state.
If people want to create satellites with only a small proportion of a country's cores they should be allowed to, so long as any benefit the game associates with it like reduction of militancy is reduced commensurately.
