It would only generate a separate entry in the database if eg there were 5 screw copies of a game with hangtabs and a 2nd release with 5 screw but no tab.
And there are examples of that from what I can tell but it's literally all over the place. From one of those links:
5 screw carts came with hangtab boxes.
5 screw carts came with boxes without hangtabs and no rev-a
3 screw black box carts have been confirmed in hangtab boxes (dk jr math)
3 screw carts came with boxes without hangtab and no rev-a
5 screw carts came with boxes without hangtab and with rev-a (MTPO)
5 and 3 screw carts came with daytime rad racer
5 and 3 screw carts came with no banner ring king
5 and 3 screw carts came with white outline lunar pool
5 and 3 screw carts came with early acclaim games
5 and 3 screw carts came with LJN Jaws and Gotcha no rev a
5 and 3 screw carts came with Konami double dribble, top gun and track and field.
5 screw castlevania, both label variations came in hangtab box - hangtab box has slight art shift on back between variations.
3 screw castlevania w/o security screws came with no rev a box
the 1987 cross over is all over the map. I could keep going...
