Any need to fix bent rim?

I had a front end alignment today and got some new front tires, and discovered one of my wheels is bent in on the inner edge. Looks like I hit a bump a little hard. I think its from tackling a 6" curb after losing the rear end on an icy turn...but that was at least 15,000 miles ago.

My alignment is in spec fine, not losing any air pressure and I dont get any vibration or anything coming from it... Is there any real reason to replace the wheel?
