Yes, maybe somtimes it's easy to reproduce a bug and even a stupid idiot can make it without a trk.
But, if they ask for it, if there is a rule or a guide line, maybe there are also reasons for it. Maybe you don't know the reason or maybe you don't understand it, but you can show some respect to these guys anyway and trust they can do their job well and if they ask a trk you give 'em the damn trk.
