If you're doing 15mm belts with a single pulley, you already have to machine your own pulleys from stock. You also already want to leave a nub on the pulley to touch the inner race of the bearing. So adding the counterbore for the bearing isn't THAT much harder, and it makes the entire chassis more compact to do it this way.
The extra inch of space really does help sometimes.
