Those are standard screwdrivers.

This is how I imagine the story playing out: Someone at Apple thought it would be a good idea to have fewer of those cases where someone cracked open his laptop for fun and ruined it and then was bitterly disappointed when Apple wouldn't fix it on warranty. That's a lot less likely to happen when nobody has the correct screwdriver just in the basement and has to order it from somewhere.

Whether that's the right or a useful thing to do I don't know but it's also no big deal.
