Boy, I think way too much has been made of this. Sadly, really nothing has changed in practice, they are simply compiling and clarifying what has been done forever. Yes, relatives have always been free to invite a DF'd person (unless DF'd for apostasy) to the memorial/ meetings. The ability to acknowledge a DF'd person attending the KH has been in place for years and years. Even 40 years ago I was instructed to politely acknowledge and seat the persons in the back row. There is no change in prohibited socializing.
In my part of the world ladies have been wearing pantsuits for decades, as long as not on stage. Nothing has really changed. Regarding ties and suitcoats, similarly, in warm weather especially, they were not required unless on stage. In our missionary assignment, I learned fast to not wear a suitcoat even on stage, I nearly blacked out from the tropical heat one Sunday. The CO laughed at the idea of wearing one in that heat.
Silly things like pantsuits or beards were never the reason people leave the church. The disordinate control measures and thought limiting dogma was. Sadly, this has not yet changed.
It's actually funny that many of us who simply stopped believing the dogma are reserved for harsher treatment than those who may have harmed children or robbed a bank. Once again, the ultimate sin is questioning their authority.
