My question would be - how does allowing facial hair or being more flexible on dress help them? The modernization helps them by implementing new forms of indoctrination or cost cutting measures, but I don't see how becoming more flexible on other things really helps them directly. Perhaps a case could be made that they might think that the dress/grooming restriction is limiting new membership, but I sincerely doubt that is the case. None of the changes they've made have relaxed their control for no real gain.
I hope they do relax the dress/grooming restrictions, though, because that would be a big step towards the eventual dissolution of the cult, the way I see it. Those controls are a big part of the BITE model that they use to keep members indoctrinated, so if they were to relax things it might allow a few more to wake up and leave. With AMIII at the helm, though, it seems wildly unlikely that will happen.
Changes I see as being more likely is further downsizing, consolidation of KHs and congregations, and further cost cutting measures. Maybe something like allowing online preaching to count so that they can puff up their stats. Things that reduce their costs or liquidate assets are probably going to be the biggest and most likely changes we'll see, IMO.
