Think of the orphans! When i think master/slave i think SPI master/slave, where the slaves only do as told by the master. In which case the primary/replica relationship would not be suitable, while the master/slave relationship is descriptive of what actually goes on. If we have one (in my view unoffensive, but that might be a cultural thing) term which adequately describes the relationship - why not use it?
