I am very doubtful that such a change will ever happen. Your examples of highranking brothers spouting off about meeting attendance
mean nothing! This is similar to other events such as demanding that sisters never wear pants - or that marriage outside of the "truth"
should trigger a disfellowshipping automatically. Only the opinions of the Governing Body and their lawyers carry any weight.
Dumping the inactive might mean losing "church tax" money in countries with that legal arrangement - and such a radical move could
also have unforseen legal consequences even in the US, in regard to child custody, for example.
