alt Hacker News??? We literally quoted the exact same text.
The plan does not outline what that quote does. You only have to do all of the things the quote claims you do in one of the three possible deployment flows. In "advanced flow" you don't have to do any of them.
No, you quoted some of the text. Hence my statement that you removed the context. If you read the full quote, it's clearly stating that you cannot opt-out of the update.
