(I'm not sure if this will be as much usable as in case of PBAP) Note that "incremental" is a bit misleading when used outside of the PBAP context. Traditionally, "incremental sync" means "retrieve only changes and apply them". CardDAV supports that. It doesn't support downloading without PHOTOs and adding them later. There was no need for it because current servers have no efficient way of getting contacts without their PHOTO data. You mentioned elsewhere that iCloud seems to refer to PHOTOs via URLs. In that case, such a mode would make sense.
