The two witness rule will unlikely change but I think the farthest they will ever go is;-
Victims will be "encouraged" rather than "allowed" (previously discouraged and previous to that threatened with disfellowshipping) to report to the authorities.
A woman will be permitted to have a female "confidant" with her - not to testify but to support.
Children/minors can already have a parent present throughout and this should be mandatory.
