That's a good question and it's just indicative of paranoia on my part. I tend to untaint data regardless of how it's going to be used at the present time. I don't know who will be maintaining my work in the future and what they're going to be doing with it, so rather than take any chances, I'd like to cover that up front. It's the same reason I turned on taint checking when it's not needed -- I never know who will use this script in the future.
Good question, though. It's a matter of style. I just prefer to be ultra paranoid -- after all, they're watching me ;)
Cheers,
Ovid
