moving from ‘single use mode’ to ‘multi-user’ clusters is the right thing to do, and we should do it ASAP (last year, if possible). It *is* going to hurt a LOT of people, and we need to respect that and allow users to opt-out for quite a while. We also need REALLY good docs, and error messages that can be googled along with SEO'ed solutions to those error messages.
