I agree, and we might use the following trick to avoid that with minimal disruption: -Consider the current interface "Legacy" that needs half of its methods deprecated -Move the non-deprecated methods to a new "Modern" interface -Legacy inherits from Modern Existing clients can then use Legacy with no change. New clients move to Modern, to make it clear that they don't want to use legacy stuff. Mark the whole Legacy interface as deprecated, recommend moving to Modern Existing services are explicitly registered as both Modern and Legacy. No need to redesign things, just move them around. WDYT? -Bertrand
