The announcement is something we knew was coming as even at Summit 2019 there were clear indications of what was to come.
A generous amount of advance notice has been given which means while there will be a change to the way we do things, there is no sense of panic or urgency.
@Kat Warner In my Organization, People started to learn Cloud interface after the 2019 summit and they are ready for the shift. You are absolutely correct- there is no sense of panic or urgency.
