Notable Benefits Polychaining Rev2 16 w/Rev2 16 Module - Beyond Uneeded Voices

Recent addition of Prophet Rev2 16-Voice. Are there notable benefits to polychaining Rev 2 16 Module _ given polyphony of keyboard version ?   

I don’t own a Rev2 but if I recall correctly there is no Polychain option- I think 16 voices is the max

Makes sense. Almost deleted post since when polychained, slave could not be adjusted in other ways from master.
Was initially 'mal-thinking' of tweaking slave knobs subtly for special effects.  😳
