The 'Hailstone message' is an interpretation of one or two verses at best. And I have always seen it as a warning not for worldly people, but just as another tool to scare Witnesses into not leaving the Organization.
Just as we were days away from Armageddon, then minutes and now seconds ... the Governing Body has fewer and fewer hyperboles left, to convince the Brotherhood as to the nearness of the end. Thus the appearance of this 'understanding' about a message of judgement.
But what good would it do, if it was real anyway. The telling billions of people that no matter what they do, they are soon going to die by having the flesh melt from there faces or by having their bodies crushed by oversized hail ... that is a thing that Satan would gleefully say.
No ... we are not going to hear anymore about the 'Hailstone message' if the Governing Body wants to portray their Faith as a kinder, more humanistic religion to attract the masses. Its just not compatible, with the new direction they feel the spirit is leading them.
