Yes, The sponge would alway's provide a viewing area for the shrimp which will be attracted there to feed on particulates .
Also assure's no tiny shrimp's can be drawn into the filter.
I use an aquaclear HOB on a tank holding some cherry shrimp/cardinal's and placed a sponge over the intake to prevent shrimplet's from being drawn into the filter and seem's there are alway's a few shrimp, clinging to the sponge while feeding.
