A closet is a closet is a closet. The black baffle trim there will not pass a final inspection. I hate to say this, but... put in the required trims for inspection, inform the homeowner of the fire danger that exists, then after inspection put in the baffle trims. Most homeowners after hearing the words "fire" and "closet lights" will opt to do the right thing and use the proper trim for a closet recessed light.
