I’ve posted a temporary workaround here that literally just says “make a Managed User on your account and use that instead of your main profile”.
For the time being, managed users are (obviously) incompatible with the account connections so they don’t see any of this stuff, even in Search.
Again, just a temporary workaround for whomever zero-choice is a dealbreaker.
What should actually happen here in terms of the feature is the ability to opt in or out, just like every other online feature to date.
