If I understand your question—and I’m not sure I do—this decision is up to you and/or your publisher.

Having gone to San Jose State U., I had the occasion to perform pieces by Anthony Cirrone for choir and percussion ensemble. He left the percussion reduction on the choral parts which we singers found helpful. Of course, there was a full score for the conductor but I don’t remember if the percussionists played from it or if they each had parts.

Mind you, this was all done by hand as notation software didn’t exist back then. I never asked if he did the layout or if it was a copyist but do remember the beautifully clean look of the pages.

 I would think that this is a decision as a composer to give your singers what they need for cues.
