There is a lot of talk of feature flags but that only works when you can realistically delay your feature 2 weeks so that the 'special' set of clients can see it early. What we've seen that has worked is essentially demoing the feature in staging/test to stakeholders at the major/demanding client. They are happy that they aren't taken by surprise and then we provide training materials for major feature/UI changes to their users. Never have had an issue, client is happy and essentially zero technical involvement.
