House Bill discussions using 529 funds to pay off Student Loans

Has this been discussed here? http://www.investopedia.com/articles/personal-finance/020217/can-i-pay-student-loans-my-529-plan.asp

Dang it that was my strategy when the kids started school, leaving the 529 plan till the end so it could grow and take all the subsidized loans I could. I would then pay the loans off at the end with the 529 money. Then I found out that wasn’t allowed so we started using the 529. But it’s been a juggle to use the 529 and not take too many loans but yet take enough so we qualified for the AOTC.

Now maybe for my youngest I can use my original stradegy. Plus I’d of kept adding to the 529s but I stopped. I’ll be keeping my eye on this bill.
