If they lifted or softened their rules on shunning, I don't think it will have the impact some here think it will. Do you think that your children, parents, and former friends that have shunned you for many years will all of a sudden reach out to you? They will still view you as unrepentant, mentally diseased, worldly, and bad association. I don't see a daughter or son that has shunned their parents for a decade and withhold their children from meeting their grandparents all of a sudden have a change of heart.
The Watchtower Inc. would have to give not only permission but also encourage those to reach out, and that won't happen. Every year the WT publishes the same narratives several times a year. First narrative is the example of Korah being "swallowed up" for not following Moses and that not following the Governing Body is a death sentence. Second is Jesus stating he came not for Peace but with a Sword pitching daughter against father ect.... These two are repeated over and over again every single year I was a witness, and I still see it in their literature to this day.
