I can see a slow shift to a more "conscience" driven approach to shunning. If that happens you will begin to see more articles and convention talks about "reaching out with mercy and understanding" as a way to bring those who left because of doctrinal or procedural disagreements.
I have heard that there will be "reach out" programs first to disassociated ones and then those who committed some carnal sin many years before. It makes no sense to block out elderly former JWs who were DFd 30 years ago for "fornication." Many of them couldn't recommit that sin now if they wanted to while others have become stable parents and married partners for years - so have "repented" by their actions (or health), if not by repeating words of repentance before a judicial committee.
I do believe that we will see in the relatively near future a "special ministry" directed to those who have been forced out and shunned by their families. Shunning of family members could be relegated to a "conscience matter" (as the Watchtower already claims it to be when asked by media or courts). Removing the threat of judicial action against those who refuse to fully shun someone could be justified. My mother and father would not shun me when I showed up at their door, but their conscience would not allow them to come and stay in my house or go out of their way to "invite" me to their home. My father was an elder for many years and as far as I know never was reproved for allowing me to visit him. My sister and niece followed the same pattern most of the time - but they would "harden their hearts" at various times after the Watchtower would clamp down.
Agree or not with my suggestion, but I do see some movement toward relaxation coming in the next five years. Too many JWs are being disfellowshipped or disassociating themselves and leaving - and then deciding that the whole JW experience is not worth fighting to rejoin - even if it means disconnection from loved ones.
