For me it depends on release. If it's something handmade and special, hand numbering each copy appears just fine. For normal bulk items, I don't see much point. And even less, when it's not really limited, but pressed more later on.
I think that amount of releases that are limited to small number is so huge amount, it's no longer functioning as any sort of selling point for labels as it used to be. Which used to be reason for most labels to announce size of pressing.
So in end, I'm much more interested is it GOOD, than how many was made. Can't lure me with "This is ltd 55, buy before too late" kind of things.
