Never looked at it in regards to the detritus problem.
My whole thing with standard sock holders is that they are not always easy to maintain. When you start fiddling with the setup such as extending a rigid PVC pipe down lower into the sock to quiet them down and having to make a make shift over to reduce salt splash, now it's a chore to change them out every 3~4 days. While I've never had a purchased sump like the Trigger, I've admired from afar on the ingenuity on how easy it is to just pull a sock up and out without any obstruction and how non violently the water cascades into them vs crashing from a drain pipe. As with all great ideas IMO, it always evolves such as covers to reduce and or eliminate any salt spray, sock silencers to quiet them even further.
I guess it might not be popular or advantageous what I'm hoping for, that sump makers provide as an accessory product for reefers that utilize glass tanks as sumps or even those of us that have older sump vessels that utilized standard sock holders
