The reason it’s usually used against capitals and supers/titans is because they are big slow things that are usually flown very carefully with a keen eye on local. You hide the fleet by logging them off in a spot that you have already probed down to be a location where said capital/supercapital will be doing their thing (PVE, logoff-safespot, etc) and once you have them trapped by an interdictor of some sort, you log in the rest of the fleet.
smaller and faster ships are usually not worth the trouble of setting up a logoff-trap, unless something special is happening (rare ship, expensive fit,someone really pissed someone else off, etc) due to their ability to slip through the tackler before your fleet can land on grid.
