A couple of Hapkido guys used to come to my old Judo dojo from time to time and cross train.
I think it was incorporated. Was it changed? probably. In my Hapkido class, often more emphasis is put on grabbing the person (arms, legs, head, waist) rather than grabbing a Gi. In my BJJ class, of course, lots of Gi grabbing, probably similar to Judo. Personally, I prefer learning no-Gi grappling/submissions.
