If these policies do not end or the rules are relaxed, so many "ifs" can be inserted that in practice they will have no effect.
Let's see, the issue of blood had so many "ifs" that today like fractions, if someone takes blood, they are no longer summarily disfellowshipped, etc.
In the matter of disfellowship, there are so many "ifs" such as if the person is at risk of committing suicide, if the person has been inactive for a few years, if the person threatens to sue, etc. In any "if" the JC is suspended. The two-witness policy itself can be reversed, not being used for pedophilia and being used to avoid disfelloship for other reasons. Perhaps there is no need for a formal announcement from the GB on the issue of DF flexibility, it is enough more policies to be silently implemented in the book of elders. And then just a few studies of The Watchtower, explaining the DF texts better, explaining the context and leaving it up to the congregation not to invite the person to theocratic activities as a form of censorship (which is more or less what the texts they use say) , but not avoiding to greet or force someone to cut family ties.
