Yes, I think the problem between the 2 is the campsites are cheap enough that it's a common thing for people to do. 2 tickets for a day's admission, not as cheap and fewer are going to do it.
Here's why I don't think DW will ever bother do close the loophole, no one makes money off of it. They closed this current one when people made money by selling "tours" using it. They did the same with the old GAC abuse. When someone found a way to monetize it, they dealt with the abuse. Not before. Until, or unless, someone finds a way to monetize this, they'll leave it alone.
The only other way they address it is from complaints from people who want to camp and can't and can prove that a large number of camp sites are booked and unused. If Disney got enough complaints then they may address it. For the camp sites.
