About five years ago a witness in our area died. Knowing she had a disfellowshipped nephew, our congregation had a local needs part about not attending a funeral reception if a DF'd person was there. The congregation nearby forgot to do their local needs part, so the wife of one of the elders called most of the publishers to let them know how they should behave if he should show up.
Just by chance, the DF'd nephew's wife gave birth the night before the funeral so he didn't attend. I think there would have been a lot of repercussions if he had.
