Yes, unless the programs and service programs are intended to go outside your control, and somebody tries to use a new program, expecting a new call to be available, with an old version of the service program that lacks that call. Just as there's a reason for signatures, and a reason for allowing the developer full control over them, there's also a reason for having *previous and *current signature support.
